If one where to strip the electrons from, for example, hydrogen or deuterium (which is easy enough) and then cooled it to freezing, what would be the resultant solid material?  Pure protons-but I cant imagine the physical properties of such a thing.  One would imagine, since there is so much hydrogen plasma (H+) and hydrogen oceans on gas giants, that this may occur..

when a solid is formed with hydrogen the way it is formed is by covalent/ionic bonding.  \nBecause there would be no electron covalent bonds would not be able to be formed.  also because every thing would be positivly charged it would not be possible for ionic bonds to form.  \n\nthe definition of a plasma is exactly what you are looking at.  It is the fourth state of matter, namely it is when the electrons are dissasociated from the nucli.  No matter what tempature you had it would remain a plasma.  even if it was cooled to abolute zero and pressurised with electrostatic feilds it would still remain in a gas like form for there is no way for it to solidify.  The repultion of the electric feilds would be far to great to over come the neuclear forces that would be needed to make an isotope of heleium with no nutrons.  \n\none might imagine that if you did cool it and compress it a whole bunch it would maintain some shape, but then quantum mechanics take over and the protons would be switching possitions constantly.  \n\nalso the possitive charge of the proton star would be incredible, remeber that it takes only one in a thousand electron to make a substance very highly electricly charged... we are talk a thousand times more than that it is impossible to even imagine what the effects would be

It isn't air! When water freezes all dissolved gases & other matter are not included!!! \n\nThe hydrogen bonds that form when water freezes creates an open structure. There is simply nothing in between those spaces.\n\nWe are talking about molecular structure, things at this level are so tiny that even thinking about what is in between is silly.\n\nIf there is anything between the spaces it is probably interstitial water molecules (those not hydrogen bonded inside the crystalline lattice structure - think of them as loose molecules of water).\n\nIce floats on water because it has expanded. That is all. Not because of what is in between the "spaces".\n\nSee, when you increase the surface area but have the same number of molecules present, you cause the object to become less dense. (it's less tightly packed...things that are tightly packed for their size are said to be more dense.)

Plasma is a state of matter when the bonds between molecular particles are broken and subatomic particles are all lumped in together. This condition of matter is achieved under extreme temperatures and pressures, typically in stars. Most of the mass of our Sun is composed of plasma matter also.

Water, when heated from a solid to liquid state, but ultimately in a gaseous state it again expands.  It still obeys all the laws of chemistry, but the bonds just arrange themselves in a more space efficient manner in liquid than in solid form.\n\nAnd moses with a P, no metals exist with the properties you say.  It is physically impossible, sorry man, but I'm a biochem major and it's my job to know what stuff does under different stresses, and nothing does what you claim.  However, if you do have a material that does this, get in touch with me, we'll talk to the patent office, and we'll license it out to companies for billions of dollars.

Have you heard of boiling and freezing points. Each substance has a boiling and a freezing point there is a different one for each substance. The freezing point of H20 (hydrogen and oxygen) is 32 degrees Fahrenheit and the boiling point is 212 degrees Fahrenheit. Now these temperatures could be different if the water has anything else in it changing the molecular structure. Things like salt, calcium, ect. So in your bottle story....The gas (common air) which has things like helium, carbon and oxygen is on top and your water is on the bottom. This could get confusing but essentially when you shake it up you added other molecules into the water that have a lower or higher freezing point. Same idea as when you have a partially frozen bottle of water and you shake it up and it defrosts. It also has to do with the first law of thermodynamics...Energy can not be created or destroyed just transferred. So some molecules do not have enough energy to bond with one another but when you shake up the bottle it transfers energy allowing them to bond with one another. Hope I didn't confuse you too much.

answer can be a or c, but i'd go with answer c.\n\nthe melting point (which solid becomes liquid) varies by each molecules & substances.  What happen is when temp. rises, it translates into more energy put into the soild or heat absored by the solid.\n\nHowever, you can melt solid by chaning pressure, and leaving temp constant.\n\nSo best answer would be C, by heat absorption.

How exactly are you splitting the H from the O?   Under high pressure and spraying?  I don't see how that could possibly work.  Cold fusion also has a huge potential for cheap, clean, renewable energy.  But much like what you are talking about, it simply isn't possible with the current technology.  If splitting H and O was so cheap and simple it would be done all of the time.  Electrolysis works, but the energy input makes it unrealistic for creating liquid hydrogen as an energy source.  If you truely have a way to spit the H20 molecule cheaply and efficiently you'd already be a multi-billionaire.

It is just one of the properties of the H bonding of water and the type of crystal lattice it forms. Also not all ice is less dense than water.  If you froze water with tritium or deuterium instead of regular H the ice would sink.\n\nAlso water reaches it maximum density as it approaches its freezing point.

Do not offer bribes, this is immoral.\nMany here come to assist as a service.\n\nYour answer is here:\n\nWhen ice melts, kinetic energy of H2O molecules is increased by absorption of heat energy from the surroundings.\n\nHowever as the kinetic energy is increased to make the molecules move freely, Hydrogen Bonding among the water molecules becomes more effective and so a particular intermolecular distance is maintained among the molecules. \n\nThis is effective upto 4C.\n\nAfter 4C the H-bonding becomes so week as against kinetic energy that free movement of molecules is no more restricted and thus abnormal behaviour of water molecules is stopped.

The melting point of a crystalline solid is the temperature at which it changes state from solid to liquid. When considered as the temperature of the reverse change from liquid to solid, it is referred to as the freezing point.\n\nFor most substances, melting and freezing points are equal. For example, the melting point and freezing point of the element mercury is 234.32 kelvins (−38.83 °C or −37.89 °F). However, certain substances possess differing solid-liquid transition temperatures. For example, agar melts at 85 °C (185 °F) and solidifies from 32 °C to 40 °C (89.6 °F to 104 °F); this process is known as hysteresis. Certain materials, such as glass, may harden without crystallizing; these are called amorphous solids.\n\nThe melting point of water at 1 atmosphere of pressure is 0 °C (32 °F, 273.15 K), this is also known as the ice point. In the presence of nucleating substances the freezing point of water is the same as the melting point, but in the absence of nucleators water can supercool to −42 °C (−43.6 °F, 231 K) before freezing.\n\nUnlike the boiling point, the melting point is relatively insensitive to pressure. Melting points are often used to characterise organic compounds and to ascertain the purity. The melting point of a pure substance is always higher than the melting point of that substance when a small amount of an impurity is present. The more impurity is present, the lower the melting point. Eventually, a minimum melting point will be reached. The mixing ratio that results in the lowest possible melting point is known as the eutectic point.\n\nThe chemical element with the highest melting point is tungsten, at 3695 K (3422 °C, 6192 °F). The often-cited carbon does not melt at ambient pressure but sublimates at about 4000 K; a liquid phase only exists above pressures of 10 MPa and estimated 4300–4700 K. Tantalum hafnium carbide (Ta4HfC5) is a refractory compound with a very high melting point of 4488 K (4215 °C, 7619 °F).[1] At the other end of the scale, helium does not freeze at all at normal pressure, even at temperatures infinitesimally close to absolute zero; pressures over 20 times normal atmospheric pressure are necessary.\n\n\n--------\n\n\nThe boiling point of a substance is the temperature at which it can change its state from a liquid to a gas throughout the bulk of the liquid at a given pressure. A liquid may change to a gas at temperatures below the boiling point through the process of evaporation. Any change of state from a liquid to a gas at boiling point is considered vaporization. However, evaporation is a surface phenomenon, in which only molecules located near the gas/liquid surface could evaporate. Boiling on the other hand is a bulk process, so at the boiling point molecules anywhere in the liquid may be vaporized, resulting in the formation of vapor bubbles.\n\nA somewhat clearer (and perhaps more useful) definition of boiling point is "the temperature at which the vapor pressure of the liquid equals the pressure of the surroundings."\n\nThe reaction\n\nSomething that should not emembered is that boiling is evidenced by the appearance of bubbles containing vapor from the liquid. [Note: The bubbles that precede real boiling in the pot on the stove are either (formerly) dissolved gas or water vapor forming on the very hot bottom of the pot that will be condensed before it can get to the top of the liquid.] Production of vapor requires energy and thus does not occur without some source of energy. This source can be a hot surface or even the liquid itself. Hot liquid will boil as it rises through the bulk liquid if the pressure of the environment drops to the vapor pressure of the liquid at its temperature. This production of vapor will not quickly stop because the temperature of the liquid will not be reduced by the vaporization thus reducing the vapor pressure.\n\nSaturation temperature and pressure\n\nA saturated liquid or saturated vapor contains as mu

Of all the answers you have there, d) is the most correct.\nA molten core helps, but is not necessary, as Jupiter likely has no molten core - just metallic hydrogen.

Good. Tritium has 2 neutrons and 1 proton where-as deuterium has one proton and one neutron. When they fuse they form Helium-4 which has 2 neutrons and 2 protons. This reaction releases one neutron and heat (as it's an exothermic reaction). Imagine tons of tritium and deuterium fusing, that's a lot of heat isn't it? It's the heat that does the damage. But it's hard to set it off. You'll need a small fission bomb to set off the fusion reaction.

first of all, the experiment has not been done yet, we have not been able to reach absolute zero yet.  gases liquids and solids are properties of atoms and their compounds and have to do with intermolecular forces. in liquids and solids, the atoms are touching(solids they are stuck in place liquids they slide over each other) but regardless, 2 electrons(both being negatively charged) can never touch. that doesnt mean they are a gas, because these phases of matter do not apply to plain electrons. subatomic particles do not experience these phases or phase changes. At absolute zero(which hasnt been reached and thus is still theoretical), all matter would stop moving, so the electrons would stop moving and lose all kinetic energy.

Hmmm....\n\nYour science grade cannot be helped if you can't figure out that Hydrogen, a gas, is not an alkali metal.

Absolutely.  In fact, there have been several different approaches, including zapping little pellets with a monster laser (NOVA), which are then immersed in water.  These minuscule nuclear bombs fuse and release their energy into the water, creating steam and turning turbines.\n\nThe most promising method, however, is a fusion reactor; a magnetic bottle which traps plasma.  Fusion occurs when the electromagnetic forces of nuclei (which are positive) are overcome.  In order to get nuclei, atoms are injected into the reactor and brought to immense temperatures.  The individual atoms, which are neutral, become so energetic that the electrons are stripped from the nuclei, creating plasma.  Plasma is simply free electrons (negatively charged and unbounded to a nucleus) and the positively charged nuclei.  Because these are positively and negatively charged, the plasma is contained within magnetic field lines.  This is the proverbial "magnetic bottle".\n\nThe nuclei smash into each other, creating helium nuclei and excess neutrons.  These neutrons are EXTREMELY energetic (14 MeV), and are neutrally charged.  Therefore, these neutrons zip right past the magnetic field lines.  The charged plasma remains, continuing the fusion process; and the neutrons are captured in water, where elastic collisions with H2O molecules transfers the energy from the neutrons to the water, heating the water, turning it to steam, and turning the turbines.\n\nThere are a couple of major problems.  First, the sun is very big and very hot.  Getting similar temperatures and pressures on Earth is next to impossible.  Although the energy released is several orders of magnitude greater than the energy put in when the process is going a full capacity, getting it started has been very difficult.  However, through TFTR and the new ITER, already the plasmas have generated more energy than were used to start the process.  This is a big step.\n\nAlso, the magnetic bottle and the plasma can experience some strange instabilities and wave functions.  Any time a harmonic resonance-like phenomena occurs, the fusion can break down, the plasma cools, and the process slows or stops.  As the test reactors continue to gather data, these phenomena are better understood.\n\nFinally, those 14 MeV neutron zip through the magnetic bottle and the water, and interact with impurities in the concrete and building materials, creating radioactive waste.  This waste is not insignificant - huge amounts of concrete becomes low-level waste.  Low level waste is NOT a measure of how dangerous it is - this stuff can be very dangerous - but it will only remain dangerous for about 100 years or so.  It's not the stuff that remains deadly for thousands of years.\n\nSo solve the instabilities, be able to sustain a plasma and reaction long enough to become self-sustaining, and be prepared for the low level waste, and fusion will become an almost unlimited energy supply.

you must be more specific...\n\n- what atom are you considering?\n-what type of structure? There are several different types of models to consider...Bohr model? Planetary model? Lewis structure? \n\nIn any of these cases, I'm guessing you have to draw the nucleus with protons and neutrons and the correct number of electrons...but it's hard to be too specific w/o knowing what you're looking for...
