Question

how does lead react to air

Answer 1

Explanation:

Lead reacts with air, in the presence of moist and carbon dioxide, forming a passivating layer. The layer is most likely lead hydroxy carbonate [8].

Answer 2

Answer:

The surface of metallic lead is protected by a thin layer of lead oxide, PbO. Only upon heating lead to 600-800°C does lead react with oxygen in air to from lead oxide, PbO. Finely divided lead powder is pyrophoric, however, meaning it is a fire risk.
