# What is the octet rule of sulfur?

Feb 8, 2014

The octet rule is the understanding that most atoms seek to gain stability in their outer most energy level by filling the s and p orbitals of the highest energy level with eight electrons.

Sulfur has an electron configuration of $1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {P}^{4}$ this means that oxygen has six valence electrons $3 {s}^{2} 3 {p}^{4}$. Sulfur seeks out two additional electrons to fill the p orbital and gain the stability of a noble gas, $1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {p}^{6}$.

However, now Sulfur has 18 electrons and only 16 protons making it a -2 charge anion ${S}^{- 2}$.
