Excited State
State in which an electron has a higher energy than it normally should
Orbital
Three-Dimensional space around the nucleus that indicates the probable location of an electron of certain energy
Photon
Quantum of energy
Frequency
Number of waves that pass a given point in a specific time
N
Tells the energy level of the electron
M
Tells which orbital in a set of orbitals
S
Tells the spin of the electron
