Answer:
The surface of metallic lead is protected by a thin layer of lead oxide, PbO. Hence, it does not react with water under normal conditions.
So, under normal conditions lead does not react with water. However, when lead comes in contact with moist air reactivity with water increases. A small lead oxide (PbO) layer forms at the surface of the metal. When both oxygen and water are present, metallic lead is converted to lead hydroxide (Pb(OH)2):
2Pb(s)+ O2(g) + 2H2O(l) -> 2 Pb(OH)2(s)
