Respuesta :
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.
