difference between metal and non metal by quoting 5 properties of each
Answers
Answer:
METALS:-
1) all metals are solid at room temperature except mercury, which is a liquid at room temperature.
2) all metals are lustrous.
3) metals have high densities except lithium, soduim and potassium.
4) metals are malleable (can be beaten into thin sheets).
5) metals are ductile (can be drwn into wires).
6) they are good conductors of heat and electricity.
7) they have high melting point.
NON-METALS :-
1) non-metals exists as solid, liquid and gas.
silicon is a solid, bromine is a liquid and oxygen is a gas.
2) non-metals are non-lustrous.
3) they have low density.
4) they are non-malleable.
5) they have low melying and boiling point.
6) they are poor conductors of heat and electricity.
7) they are non-ductile.

Metals Non-metals
Metals are electro-positive. Non-metals are electronegative.
Metals reacts with oxygen to form basic oxides.

Metal oxides and hydroxides bonds have ionic bonds. Non-metal oxides and hydroxides have covalent bonds.
Metals react with water to form hydroxide and hydrogen.

Non-metals do not react with water.
Metals react with dilute acids to form salt and H

. Non-metals do not react with dilute acid and they can not displace hydrogen.
Metals react as reducing agent by donating electrons.
