The electron configuration of an atom specifies the occupation of its orbitals. The atomic orbitals (AOs) are labeled by a principal quantum number n = 1, ..., 7 and a letter that is in one to one correspondence with its angular momentum quantum number l:

See hydrogen-like atom for a further explanation of this notation. See this article for the source of the AOs and the building-up principle. A table of atomic electron configurations of all natural elements is given below in increasing atomic number. The following table is a linear form of the Periodic Table of Elements.
