What are the major differences between metals and non-metals?

Explanation

(1) Metals are usually solids at room temperature. Metals have high melting and boiling points. Metals are good conductors of heat and electricity. Metals are malleable and ductile.
(2) Non-metals are usually solids or gases at room termperature. Non-metals have low melting and boiling points. Non-metals are poor conductros of heat and electricity. most non metallic solids are brittle and are neither malleable nor ductile.
