Question

Draw dot and cross diagram for following compounds: Mg3N2,

Answer 1

Explanation:

Here,

Mg has two Valence electrons so two dots are shown

and, N has five Valence electrons

so, first Mg shares twoelectron with N

and second Mg shares one electron to first N

and second Mg shares his second electron with N

and third Mg shares two electrons with N

Here, by sharing electrons N complete his octet i.e. eight electrons .
