Question

How many Valence Electrons are there in Argon?

Answer 1

`8`

Explanation:

Argon is a noble gas with an electron configuration of `[Ne]3s^2\3p^6`. So, it has `3` electron shells, and that will be its valence shell.

In the third shell, it holds a total of `2+6=8` electrons, so it has `8` valence electrons.
