Understanding the Chemical Formula

The chemical formula $Ni \left( NO _3\right)_2$ represents a compound consisting of nickel (Ni) and nitrate (NO3). To determine the number of nitrogen atoms in this compound, we need to break down the formula and identify the individual components.

Breaking Down the Formula

The formula $Ni \left( NO _3\right)_2$ can be broken down into two main components:

  1. Nickel (Ni): This is a single atom of nickel.
  2. Nitrate (NO3): This is a polyatomic ion consisting of one nitrogen atom and three oxygen atoms.

Counting the Nitrogen Atoms

Since the nitrate ion (NO3) contains one nitrogen atom, and there are two nitrate ions in the formula (indicated by the subscript 2), we need to multiply the number of nitrogen atoms in one nitrate ion by 2.

Calculating the Total Number of Nitrogen Atoms

1 nitrogen atom in 1 nitrate ion × 2 nitrate ions = 2 nitrogen atoms

Conclusion

Based on the chemical formula $Ni \left( NO _3\right)_2$, there are 2 atoms of nitrogen in the compound.
