weight

=

14

4.2

=0.3 moles

0.3mol =0.3×N

A

ions

Number of valence electrons present in one mole of N

3−

=8

Valence electrons present in 0.3 moles of N

3−

=8×0.3×N

A

Answer 2

The electron configurations of ions are those of the neutral atoms plus or minus a number of electrons equal to the charge on the ion. Write the electronic structure for the neutral atom. Then add electrons to get a total of eight.
