What are the differences of metal and non metal?

Answer 1

Metals are good conductors of heat and electricity, are ductile, malleable and shiny, and most of them are solid (except Mercury).

A non metal is a bad conductor of heat and electricity, are not malleable, ductile or shiny, and can be a solid, liquid, or gas.

Answer 2

Metals generally have high electrical conductivity, are malleable, and exhibit metallic luster. Non-metals typically have low electrical conductivity, are brittle, and do not have metallic luster. Metals tend to lose electrons to form positive ions, while non-metals gain electrons to form negative ions.
