#Mg^(2+)# and #(O=)N^(+)(-O^(-))_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 #/_O-N-O# #=# #120^@#.
