What is Radiation and what is electricity?

I did college level chemistry and remember something about the reason why luminescent radioactive paint such as that used on clock faces are luminescent. This is because the atoms of the paint are unstable and the electrons orbiting the atom nucleus are jumping orbits and releasing energy which is in the form of light and radiation.



I tried basic physics and couldn't do it, but becuase of chemistry I worked out that electricity is the free flow of electrons along a material, don't know if this is right.



If both the above are accurate then both radiation and electricity are down to the action of electrons and so are related forms of energy?!What is Radiation and what is electricity?
Here's the simplest way to understand electricity.



Materials made of atoms (matter), have many atoms. Each has a nucleus of protons and neutrons. The electrons orbit outside of that nucleus, like miniature planets around a miniture sun.



Some of the electrons in the "outer orbit" (valance band) are free. That is, they can be torn away. If the material is a conductor, you have a whole lot of these.



Now all you need is a potential diffferance. That's the same thing as voltage. Just means you have UNEQUEEL charge (# of free electrons) in one place vs. another in the material. So electrons flow to where the charge is most positive until everything equeels out.



Of course, if you have a motor or a battery or a generator - the Potential Differance (voltage) DOESN'T equeel out. The voltage source keeps that from happening - so you have continuous electricity.



That flow of electrons is called "current."What is Radiation and what is electricity?
they're certainly related but not very closely.What is Radiation and what is electricity?
radiation is actually propagated in three different forms

1-alpha rays

2-beta rays

3-gamma rays

-alpha rays are 2 protons and to neutrons(like a He2+ ion)

-Beta rays are electrons(or positrons) that are liberated from the nucleus by neutron decay.

-gamma rays are highly energetic photons(principle particle of electromagnetic radiation)having very high penetrating power.

now for electricity

electricity is basically the flow of electrons from one point to another due to differences in the voltage.



now if you try to equate together the fact that Beta rays are ordinary electrons the main differences are

-Beta rays are produced in the nucleus.

-They are much more energetic than ordinary electrons bound to an atom

-they are free from the atom and move not around a nucleus but instead in definite paths.



hence radiation and electricity cannot be considered the same at all.allthough they can be interconverted.
