Metals are sometimes described as a lattice of positive ions surrounded by a cloud of delocalized electrons. ... The traditional definition focuses on the bulk properties of metals.

A nonmetal is an element that is generally a poor conductor of heat and electricity. Most properties of nonmetals are the opposite of metals.

)The metals are generally present in the solid form at room temperature except mercury which is liquid at room temperature. Whereas non-metals may be solid, liquid and gaseous at room temperature.
Metals are good conductors of heat and electricity but non-metals are poor conductors of heat and electricity.
Metals are ductile in nature i.e. it can be drawn into thin wires. But non-metals are not ductile.
Metals contain 1 to 3 electrons in their outermost shell whereas non-metals contain 4 to 8 electrons in their outermost shell.
Metal loses electrons to form electropositive ions but non-metals accept electrons to form electronegative ions.
Metals have low ionization enthalpy and non-metals have high ionization enthalpy.
Metals react with oxygen to form basic oxides whereas non-metals usually react with oxygen to form acidic oxides.
