# What is the electron configuration of an element with atomic number 16?

May 19, 2018

$1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {p}^{4}$

#### Explanation:

Sulfur number 16 has an electron configuration similar to Oxygen
both with 4 p electrons. This electron configuration lends itself to a -2 charge as the 2 unpaired p electrons bond and share electron density with the extra electrons from other atoms.

Because sulfur has a lower electronegativity than Oxygen the electron configuration of sulfur can result in a +2, +4 or +6 charge as well as the -2 charge.

The first shell has 2 electrons
The second shell has 8 electrons
This total of 10 electrons leaves
The third shell with 6 electrons for a
total of 16 electrons.

$1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {p}^{4}$
