Question

In the compound `PCl_3`, how many total valence electrons are present?

Answer 1

`26`

Explanation:

Valence electrons on each `P` atom: `5`
Valence electrons on each `Cl` atom: `7`

Number of `P` atoms: `1`
Number of `Cl` atoms: `3`

Number of valence electrons per molecule of `PCl_3` = `5 + 3(7)` = `26`
