Answer 1

Explanation:

On the basis of physical properties , metals are classified as very hard except sodium while non metals are classified as soft except diamond. Metals are malleable and ductile whereas non metals are brittle and can break down into pieces.

hope it's helpful

Answer 2

Difference between Metal and non metals on the basis of physical properties:-

Metals:-

• Metals are ductile and melleable.
• Metals are good conductors of heat and electricity . Silver and copper are best conductors of heat and electricity. Mercury is bad conductor of them.
• Metals are lusture. eg - aluminum and magnesium appear white gold is yellow.

Non metals :-

• Non metals are neither ductile nor malleable.
• They are bad conductors of heat and electricity except graphite. ( an allotrope of carbon ).
• They are non lustrous and cannot be polished except iodine.
