He didn't actually do the experiment, he supervised it.  It happened in 1909, and you can read all about it here:\n\nhttp://en.wikipedia.org/wiki/Geiger-Marsden_experiment

I'm just adding on to icarus62. If an electron\nbehaved totally as a particle, then the resulting pattern\nbehind a shield with 2 slits should look like it would\nif the shield were made of steel and the 2 slits each\nallowed bullets to go thru and a machine gun were fired\nat the slits. But it doesn't. It looks like a pattern \nresulting from a radio wave that was beamed at it.

In theory, yes.  You create a new element each time you add one more proton to the previous one.\n\nIn practice, there seems to be a practical limit to the stability of the artificial elements that requires exponentially increasing amounts of energy to create the heavier artificial elements.  And since these new elements are usually only stable for tiny fractions of a second, we can't hold them in place for long enough to pump another proton in.\n\nInstead, what physicists do is take larger stable atoms and smash them together, and then look for signs of new elements based on their expected decay particles.

Here the concept is U'll decide the logic 1 nad 0 based on  spin of electrons...currently HP is working on it...if they come up with big result, it'll b a revolutionary change n da VLSI industry

The alpha particles have a positive charge. A magnet  would deflect them away from the others.

I know someone in this research area. Info can be found at...\n\nhttp://www.fusionpower.org/\n\nI'd like to say that within 100 years some kind of clean(er) energy will be produced at the atomic level.\n\nBut the hurdles associated with Fusion, really do seem insurmountable at this time.

We did a similar lab in my math class. It will be about half whenever you flip 100 pennies, then half again, ect... This is roughly the same thing as the radioactive element ("half-life").\n\nNow, make sure you do the work so you will know the material, and explain the relationship in words your teacher would like to see.\n\nGood luck.

James Randi is offering a prize of over 1,000,000 $US for anyone who can prove psychic powers in a controlled experiment.  \n\nCan you think of anyone who could do telekinesis who couldn't use a million dollars?  \n\nMe neither.

Your question is a sentence using the word.\n\n"What is a sentence using the word foil?"

Surprisingly it is. See the both enclosed aticles about the theory and experiments done to prove it. In reality human mankind will not have the ability to do it for a long time.\n\nVery simplified it would work like this:\n\nIn an atom always 2 electrons on the same circle are linked. One has to have a up-spin, the other has to have a down-spin. But you do not know which one has it. Kick the elctrons out of the circle and send them into two directions. \n\nWhen you know measure the spin of one you know exactly the spin of the other one. If you would be able to manipulate one the information would be transfered immediatly to the other on. This has been done in laboratories.\n\nEInstein predicted this but nobody really believed it would work, the science community is still under a certain shock.\n\nThe challenge is to do this with all the electrons of you body.\n\nBut ther is a practible application for this. The speed of comuter today is "slow" because information is transfered in form of electrons which move in metals inside the chips, the next step would be to transport the information by light whcih is significant faster and the next step would be a "quantum-computer" where the information is transfered in the above menioned form. This would reduce the time to calculate any problem in an unbelievable way and calculations which are not possible today could be done.

Hi again,\n\n    Well you see, as you know electrons are added up in the 3d orbital in galium, right? So with the increase in number of electrons, the no of protons i.e atomic number also increases. So now the outermost p electron in Al is attracted by 13 protons. But that in galuim is attracted by 31 electrons. So the force of attraction is much more. Now in other atoms, these outer electron attraction is balanced by counter electron electron repulsion. But the added d electrons  cannot shield the outer p electrons much from the force of attraction of the highly charged nucleus. This is similar to the reason why the transition elements contract on increase in at no. Other examples are lanthanide and actinide contractions. If you still dont get it,\nmeet me on Yahoo Messenger. My id is jchemisch. I will talk to you about it. All the best. Hope i can help you if you need!!

Yes, and I wish I could find that link I read years ago.  The above methods are acceptable, but this method used up “A LOT” of energy, and was not perfected.  When I worked at NASA years ago there was a joke about it. Now there is something to it they have found.  Like anything else you through enough money at it you will get something out of it.  So for your government money watchers I recall something like only 5 to 8 % of this research budget comes from government grants. It really does not have any military value as of yet.

Rutherford and Bohr did much of the early theoretical work on the structure of the atom but the real breakthrough was in 1938 when the Austrian physicist Lise Meitner and the German chemist Otto Hahn bombarded uranium with neutrons and caused it to splinter into barium and krypton. \n\nShe coined the term "fission" for this process. borrowing a term from biology. When the Nobel Prize was awarded for this joint work over 30 years, after WW2, he was awarded it and she was omitted. Being female and Jewish had caused her career to be eclipsed by his.

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.

It is just a reference to E=mc^2.  It can be through fission or fusion, so yes you are surely correct.

Cool.\n\nUse the FOIL method. First, outside, inside, and last.

Edward Teller,the father of the hydrogen bomb,developed the neutron bomb back in the 70's.The Soviets viewed it as a first strike weapon so it was never deployed because we feared the Soviets would strike first to prevent us from striking first with our 'clean' bomb.Kind of stupid isn't it.
