What are the differences between metals and nonmetals (on the basis of their chemical properties)?

Ans.

Metals
Nonmetals
They generally form basic or amphoteric oxides.
They generally form acidic or neutral oxides.
Highly reactive metals such as Na, K, Ca, Al, Fe, etc. displace hydrogen from water or steam.
Nonmetals generally do not react with water.
Highly reactive metals displace hydrogen from dilute acids.
Nonmetals generally do not displace hydrogen from dilute acids.
Metals have strong tendency to lose electrons and hence, they behave as reductants or reducing agents.
Nonmetals have strong tendency to accept electrons and hence, they behave as oxidants or oxidising agents.
