Electron configuration notation describes the energy levels, orbitals, and the number of electron. The number and letter describe the energy level and orbital respectively, and the superscript number shows how many electrons are in that orbital.
Electron configurations have the format: 1s2 2s2 2p6 . The first number is the principal quantum number (n) and the letter represents the value of l (angular momentum quantum number; 1 = s, 2 = p, 3 = d and 4 = f) for the orbital, and the superscript number tells you how many electrons are in that orbital.
