What are the valence electrons in MgCl^+, CO_2, and HF?

May 23, 2017

Well magnesium is an $\text{alkaline earth}$, i.e. a $\text{Group 2 metal cation}$....

Explanation:

And so for $M g C {l}^{+}$; you possibly meant to write $M g C {l}_{2}$, i.e. $M {g}^{2 +} + 2 \times C {l}^{-}$.

For $C {O}_{2}$, we have $4 + 6 + 6$ valence electrons to distribute; i.e. 8 electron pairs:

$: \stackrel{. .}{O} = C = \stackrel{. .}{O} :$

And for hydrogen fluoride, we have $1 + 7$ valence electrons, i.e. 4 electron pairs...........

$H - F$.
