Question

Describes the difference between the formulas for nitrogen monoxide and nitrogen dioxide?

Answer 1

nitrogen monoxide: NO

nitrogen dioxide: NO₂

Step-by-step explanation:

Nitrogen monoxide is composed by 1 atom of O (prefix "mono-") and 1 atom of N. Nitrogen dioxide is composed by 2 atoms of O (prefix "di-") and 1 atom of N. As the oxigen atom in oxides has the valency -2 (it shares 2 electrons), the nitrogen has valency +2 in NO and +4 in NO₂.
