# What is the Lewis structure of compound Mg(NO_3)_2?

Apr 18, 2016

$M {g}^{2 +}$ and $\left(O =\right) {N}^{+} {\left(- {O}^{-}\right)}_{2}$

#### Explanation:

Of course, magnesium nitrate is an ionic species. The Lewis structure of the nitrate anion is as given above. The nitrogen is quaternized, and bears a formal positive charge, and 2 oxygen atoms are formally negatively charged. Because there are 3 regions of electron density around the nitrogen atom, it has trigonal planar geometry and $\angle O - N - O$ $=$ ${120}^{\circ}$.
