# What is the valence electron configuration for sodium?

##### 1 Answer
Feb 8, 2014

The electron configuration for sodium is $1 {s}^{2} 2 {s}^{2} {p}^{6} 3 {s}^{1}$
This means that sodium has a valence shell of $\left[N e\right] 3 {s}^{1}$.

The valence level, (highest energy level s and p orbital) is $3 {s}^{1}$

Sodium has one valence electron.

I hope this was helpful.
