1. Chemical Formula:
* Lead(II) nitrite has the chemical formula Pb(NO₂)₂.
2. Breakdown of the Formula:
* Pb: This represents one lead atom.
* (NO₂)₂: This represents two nitrite ions, each containing one nitrogen atom (N) and two oxygen atoms (O).
3. Total Oxygen Atoms:
* Since each nitrite ion has two oxygen atoms, and there are two nitrite ions, there are a total of 2 x 2 = 4 oxygen atoms in each formula unit of lead(II) nitrite.
Answer: There are four oxygen atoms in each formula unit of lead(II) nitrite.
