Here's the breakdown:

* Lead(II) indicates the lead ion has a +2 charge (Pb²⁺).

* Nitride refers to the nitrogen ion with a -3 charge (N³⁻).

To balance the charges, we need three lead ions (3 x +2 = +6) and two nitride ions (2 x -3 = -6).

Therefore, the chemical formula for lead(II) nitride is Pb₃N₂.
