How many atoms of nitrogen are in the chemical formula ni(no3)2?

2 atoms of nitrogen

The correct answer is two nitrogen atoms.

Explanation:

Hello! Let's solve this!

In the molecule of Ni (NO3) 2 there are two nitrogen atoms. This is a reaction between a compound with Nickel (Ni) that has a valence number +2, and the nitrogen acid. When the hydrogen atom leaves the acid, there is a NO3- ion, this means that it is left with a negative charge. To be able to form the molecule and make it stable we will need 2 NO3- ions.

So in total there are two nitrogen atoms
