# How do you write the orbital diagram for sulfur?

Well, we use the $\text{aufbau principle}$, and for sulfur, $Z = 16$....
And thus.....$1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {p}^{4}$; this distributes the 16 electrons appropriately. Given this configuration, sulfur commonly forms sulphide anion, i.e. ${S}^{2 -}$. Can you give the electronic description for ${S}^{2 -}$. What other element shares this configuration?
