Magnetism and Electronic Configurations

The distribution of electrons in an atom, molecule, or ion in atomic or molecular orbitals.

Electrons can be in s,p,d, or f orbital Shells.

Orbital/Shell # of electrons
S orbital 2 electrons
P orbital (Shell) 6 electrons
D subshell 10 electrons
F subshell 14 electrons

Electronic configuration can be seen easier on a periodic table
