"(Ne)3s"^2 "3p"^2

Explanation:

You noticed that "p" has the superscript 2.

That means there are 2 electrons in the "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.

"Ar" = "(Ne)3s"^2 "3p"^2
