Difference between metals and non metals.
Answers
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.
Metals are sonorous in nature i.e. produces sound when hit by an object. but non-metals does not produces any sound.

3. Metals have one two three electrons in the outer shell.
4. Metals are good conductor of heat and electricity.
5. Metals have ionic bonds.
NON-METALS:-
1. Non metals are electronegative.
2. Non metals do not react with water.
3. Non metals have four to eight electrons.
4. Non metals are poor conductor of heat and electricity.
