The name of the chemical compound Pb3N4 is Lead (IV) Nitride. The number of atoms of each element in the compound is represented by the subscript numbers, and the '-ide' suffix is used for the non-metal (Nitrogen). The Roman numeral indicates the oxidation state of Lead.
The chemical formula Pb3N4 corresponds to a compound made up of Lead (Pb) and Nitrogen (N). The subscript numbers (3 and 4) denote the number of atoms from each element present in the compound. Considering that Lead is a metal and Nitrogen is a non-metal, we use the '-ide' suffix for the non-metal in the name of the compound. Therefore, the name of Pb3N4 is Lead (IV) Nitride. The Roman numeral (IV) indicates the oxidation state of Lead in the compound.
