# Since C Cl_4 is made up of one carbon and four chlorine atoms, how many total valence electrons does C Cl_4 have?

Feb 2, 2016

$32$ valence electrons, as lone pairs or bonding pairs.

#### Explanation:

The carbon atom, $Z = 6$, has $4$ valence electrons, all of which are conceived to participate in the $4$ $C - C l$ bonds. There are $7$ valence electrons on each chlorine atom; one of these electrons participates in the individual $C - C l$ bonds. $4 \times 7 + 4 = 32$ electrons as required.

$4 + \left(4 \times 7\right) = 32 {e}^{-}$

#### Explanation:

The number of valence electrons in the molecule $\mathbb{C} {l}_{4}$ could be calculated by:

$4 {e}^{-} \text{ for Carbon}$

$7 {e}^{-} \text{ for Chlorine}$

Since there is $4$ chlorine atoms in the molecule, therefore, the total number of valence electrons would be:

$4 + \left(4 \times 7\right) = 32 {e}^{-}$
