Final answer:
PbO2 is an ionic compound consisting of lead and oxygen ions.
Step-by-step explanation:
The compound PbO2 is ionic in nature. It consists of a metal (lead) and a nonmetal (oxygen), which typically form ionic compounds. In PbO2, lead has a charge of +4 (Pb4+) and oxygen has a charge of -2 (O2-). The ions are held together by strong electrostatic forces of attraction.
