# How do you write the noble-gas electron configuration for Si?

Sep 29, 2016

${\text{(Ne)3s"^2 "3p}}^{2}$

#### Explanation:

You noticed that $\text{p}$ has the superscript $2$.

That means there are $2$ electrons in the $\text{2p}$ subshell.

The noble gas notation makes the electronic configuration short.

Notice how the noble gas notation uses the closest noble gas that comes before the element.

${\text{Ar" = "(Ne)3s"^2 "3p}}^{2}$
