What is the difference between metal and nonmetal?
Metals:
Metals are usually good conductors of heat and electricity.
They are hard, opaque, shiny, lustrous and malleable and ductile.
Metals usually form ionic bonds.
None-Metals:
Non-metals are usually good insulators of heat and electricity.
They are usually brittle and have dull appearence.
None-metals usually form covalent compounds.

Metals:
Metals are solid in nature at room temperature except mercury.
They form basic oxides.
For example, gold,silver, copper etc..,
Non-metals:
Non metals may be in solid, liquid or gaseous state.
They form oxides which are acidic in nature.
For example,oxygen,nitrogen, calcium etc..,

Difference between metals and non-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 are malleable but non-metals are not malleable. Malleable means the property through which metals can be hammered into thin sheets.
Metals are lustrous i.e. having shinning appearance but non-metals are dull in appearance.
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.
Metals are good reducing agent as it loses electrons easily from its valance shell. But non-metals are good oxidizing agent as it accepts electrons in its outermost shell.
