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?
