MSN Encarta defines it as :
electricity (noun) - energy created by moving charged particles: a fundamental form of kinetic or potential energy created by the free or controlled movement of charged particles such as electrons, positrons, and ions

In the 17-1800's, the fathers of modern electrical engineering believed there was a thing called the Aether. It was the assumption at the time that everything including the vacuum was permeated by cosmic energy in vast amounts. It was thought that one could neither create nor destroy energy, and even Einstien incorporated it into his E=MC2 equation (recently disproved). Today we call the "Aether field", Zero Point Energy, and I believe it behaves in a similar manner as wind which affects the particle-spin of the electrons, producing a magnetic field which dictates the boundaries of the flow. This would account for the necessity of electrons to exist in 2 states: quiescent, and active. What do you think?

This is for a take-home final for physical science... so far my answer is as follows:
When the gas of vapor of a substance is heated, the atoms in that substance absorb energy. The electrons will then jump from their normal ground state positions to the outer levels, which are a higher lever of energy, and this is called an “excited state.” Then, when the electrons fall back into the lower level, it emits a certain amount of energy, which is released as a quantum of light. When the light emitted from an element passes through a prism, it gives the atomic emission spectrum of the element. Each element emits a unique spectrum, which makes it easy for identification.

Am I missing anything, or is this pretty good?
