Respuesta :

There are two atoms of Nitrogen in that chemical formula.

Answer: Option (a) is the correct answer.

Explanation:

The given formula is [tex]Ni(NO_{3})_{2}[/tex]. This shows that the number of atoms present in the formula are as follows.

  • Number of nickel atom = 1
  • Number of nitrogen atoms = 2
  • Number of oxygen atoms = 6

Therefore, we can conclude that out of the given options, number of nitrogen atoms present in the formula [tex]Ni(NO_{3})_{2}[/tex] are 2.
