Answer 2

The atomicity of nitrogen dioxide is 3.

• The atomicity of a species is defined as the number of atoms present in the species
• For example, the atomicity of HCl is 2 as two atoms are present.
• The formula of nitrogen dioxide is $NO_2$.
• Here a total of three atoms are present one nitrogen and two oxygens.
• Thus the atomicity of nitrogen dioxide is 3 as three atoms are present.
