what energy source will be used to generate the spectra of neon and mercury?
105461
Neon gas and Mercury vapor are excited by high voltage to emit light, producing the light spectrum for these elements.\n\nThink neon lights and mercury vapor lights.  Both use a high voltage electrical supply.

I am going to take a guess and say the moon.\n\nNo, I am kidding, it's the Sun\n\nSolar energy can be converted in to electricity and heat.

As with all stars, the sun is producing energy by nuclear fusion.  The process involves several steps, but it boils down to combining the nuclei of 4 (four) hydrogen atoms (basically 4 protons) to form a single nucleus of helium (2 protons and 2 neutrons bound together).  Several other particles come out--a couple of positrons (like electrons, but with positive charge), a couple of neutrinos (tinier than electrons and not charged), and gamma rays (very high-energy radiation).  The positrons almost immediatley react with electrons and annihilate (like Star Trek--real matter/anti-matter reaction) to form additional gamma rays.  The energy of the gamma rays are eventually absorbed a few thousand miles below the sun's surface, heating the gas there and causing it to "boil".  At the sun's surface, this "boiling gas" releases it's energy like bubbles in the form of radiation of all different energies, mostly in the visible range, producing the light (and heat and UV for suntans and more) that travels through space to the Earth and beyond.

i do not know about an element but u do get dyes which will emit in the wavelengths u mentioned if excited by UV.

yes O2- is neon \n\nMn2+ would look like V\n\nMn2+ has 2 less electrons that Mn

This is easy. Neon is a gas with atomic weight or mass of 20g, thus one mole of Neon weighs 20g. 20g could be gotten from the periodic table.

Yes, bombard it with neutrons and it will release energy...\n\nWill it be efficient.. NO. but you can do so.

A potential answer would be the Positron (the electron's antiparticle)\n\nFor a "normal" 4H->1He fusion cycle it really depends, there are several paths that it can take, but for the sake of argument let's look at the one most common in the sun.  The excess mass that 4 hydrogen nuclei have over 1 helium nuclei is converted into energy.  Some of that energy is carried off in gamma rays - ready to use light energy, that will then interact and heat the surroundings.\n\nSome of that mass-energy is given off in positrons.  These are the anti-particle to the electron.  These particles will quickly meet up with an electron, and mutually anhilate relesing energy equal to their combined mass.  Some of the energy is carried of by neutrinos.  They don't anhilate and thus leave the system quite rapidly.

the most purest form of generating light without heat is utilized by certain creatures that "glow in the dark".  it is called "bioluminescence".  ( e.g. fireflies , luminescent bacteria etc ).  they use certain chemical reactions to produce light.\n\ncyclotron radiation also does this ( but a abstractly difficult concept to understand ).\n\ntheoretically, however, the second law of thermodynamics states that all energy transformations must "waste" a certain portion of the transformation as entropy ( or heat ) .  this is unavoidable and so ANY method of generating light MUST involve a loss in the form of heat.\n\nhope it answered your most delightful question :)

Hi, Kenny. You are asking for a lot of information. I have written a book, on the history of nuclear science and will link you to it to read online. This space here is awfully limited.\n\nThe short answer is that nuclear science allows us to generate electrical power out in space even when we are far away from stars like the sun. \n\nThere are two ways we do that:\n\n1. Nuclear reactors - just like the atomic power plants on earth, reactors depend upon the splitting of uranium or plutonium atoms to generate heat and then the heat is used to boil a liquid and turn a turbine. The turbine moves a coil of wire through a magnetic field and gives you electricity.\n\n2. Thermopyles - plutonium due to its alpha radioactive decay gets pretty hot naturally. If you put two dissimilar wires wrapped around each other in a heat source and then the other end of the wires in somewhere cold (like out in space), electrons will flow through them. This is called a thermocouple. If you put lots of those together, you have what is called a thermopyle. This kind of technology is pretty flawless and is used even for things like heart pacemakers.

Bohr's theory states that each level that the electron of hydrogen can be promoted to from the ground state are of specific energy (ie the are quantized). When an electron moves between these levels, it either absorbs or emits energy that corresponds to the energy level that the electron is moving to. The spectral lines you are talking about are the emitted radiation caused by electrons that are moving back to the ground state. They can be used to work out how much energy the levels have.

'Spectral' indicating some kind of control based on light emission?  Where will the light energy come from? (It's dark inside people).\n\nThere are already delivery systems based on dissolution, is that what you mean?

You must be after the points because it is so easy to Google this, or visit Wikipedia.\n\nBasically, the n-th ionization energy is the energy required to remove the n-th electron (starting from the outside working in) to a distance of infinity from the nucleus after the previous n-1 electron have been removed.  For example, using sodium Na, it has 1 electron in the outer ring, or valence electron.  The first energy will be needed to bump that guy to infinity.  The next electron will take more energy because it is close to the nucleus.\n\nHope it helps.

francium. mercury is technicaly not a metal, it just has a low melting point, low metling points do not make it unstable. if that were the case, then oxygen would be VERY unstable ITS ALREADY TURNED INTO VAPOR!!!
