Electrons and electromagnetic radiation.

[LogicalAcid]

Well, first of all, there are two ''kinds'' of electrons,correct? Valence, the ones furthest from the nucleus of the atom, and ''regular'', the ones most tightly bound to the nucleus. Light is generated as electrons ''spin'' in their orbitals, so if light is made when an electron is in a higher orbital, because it came in contact with another particle, it absorbed the energy of that particle and the electrons gained an orbital. Electrons can't stay in this exited state forever, and when they return from the exited state into a normal orbital, they emit photons. The frequency of the photon depends on the ''height'' the electrons fell from. If it occupied a very high orbital, the photon it emits will have a higher frequency, if it was a lower orbital (but still exited) the photon would have a lower frequency. The questions here are
-How does coming into contact with another photon make the electrons basically jump?
-If all matter has electrons ''spinning", all matter emits radiation in one of the wavelengths, but in order for the matter to emit higher frequency photons, it must come in contact with a a photon of higher energy? In shorter words, if and object was hit by gamma rays, the object would have its electrons exited to a state that once they fall they emit gamma rays?
-How do radioactive substances emit gamma rays, if they being unstable has nothing to do with electron orbitals?

Electron orbitals represent chemical energy, like TNT. Gamma rays and radioactivity represent nuclear energy, like nuclear weapons.

Er... just "two"? What about free electrons? Or what about electrons that have form pairs? This is a rather strange categorization of electrons.

Incorrect. An electron in an orbital does NOT radiate. Those are stable orbits and do not radiate. Please read our FAQ in the General Physics forum.

, so if light is made when an electron is in a higher orbital, because it came in contact with another particle, it absorbed the energy of that particle and the electrons gained an orbital.

There's so many things wrong with this. Light can be produced during an transition that follows the selection rule. It doesn't have to "come in contact" with other particles.

I have no idea where to start.

Note that just in case you are unaware of this, light can also be made NOT using atoms. Radio waves are generated out of antennas that have oscillating currents. Light sources at various synchrotron centers make light by oscillating bunches of electrons.
