Mid Term Review #11

11) What is an excited state for an atom?  How do they occur?

- An excited state of an atom is when an atom gains energy or electrons and jumps an energy level.  This state is usually unstable however.  These occur when energy is gained by an atom.  An example of this is neon lights.  They produce light because the atoms in the Neon, when given energy through an electric current, become excited.  Yes quite exited indeed.
