Verified step by step guidance1
Identify the chemical formula given: Ni(NO3)2. This represents one formula unit of the compound.
Break down the formula to see the components: Ni is nickel, and (NO3)2 means there are two nitrate ions, each containing nitrogen and oxygen atoms.
Determine the number of nitrogen atoms in one nitrate ion (NO3). Since NO3 contains one nitrogen atom, each nitrate ion has 1 nitrogen atom.
Since there are 2 nitrate ions in the formula unit, multiply the number of nitrogen atoms in one nitrate ion by 2: \$1 \times 2$.
The result gives the total number of nitrogen atoms in one formula unit of Ni(NO3)2.
