# What is the s,p,d,f configuration of argon?

Jan 17, 2014

Argon is a noble gas. It sits in the column 18 group VIIA of the periodic table.

This column is part of the 'p' orbital block and it is the sixth column of the 'p' block. argon sits in the third period (row) or third energy level of the periodic table.

This means that argon must end with a $3 {p}^{6}$ in its electron configuration (3rd row, p block, 6th column). The p block is filled with 6 electrons and all noble gases have a filled p orbital.

All other levels of the electron configuration must be filled below this level. $1 {s}^{2}$ $2 {s}^{2}$ $2 {p}_{6}$ $3 {s}^{2}$

The completed electron configuration is as follows.

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

Hope this was helpful.
