Some metals react with air and corrode. For e.g. Iron.
Metals are good conductors of heat and electricity. Lead is an exception.
Generally, metals are in a solid state at room temperature. Except for Mercury. Mercury is in a liquid state.
highly reactive metals like sodium and potassium react with water violently and an exothermic reaction takes places where the hydrogen immediately catches fire.

metal + oxygen = metal oxide
2cu + O2 = 2cuo
4al + 3o2 = 2al2o3
al2o3 + 2naoh = 2alcl3 + 3h2o
al2o3 + 2naoh = 2NaAlO2 + h2o
2cu + O2 = 2cuo
4al + 3o2 = 2al2o3
al2o3 + 2naoh = 2alcl3 + 3h2o
al2o3 + 2naoh = 2NaAlO2 + h2o
