Answer:
b) N3-
Explanation:
The octet rule stipulates that a chemical specie is stable if it has eight electrons in its outermost shell.
Nitrogen belongs to group 15. This means that it has five electrons in its outermost shell. The formation N3- means that it accepted three electrons.
This brings the total number of outermost electrons to eight in accordance with the octet rule.
You will know;
1. know what products are
2. know how they work
Valence election configuration is the electrons in the shell that equal to 8. it what forms chemcial bonds. Electron configuration is distribution of elections of an atom.
