Answer 1

Answer:

Metals and non-metals are substances that can be differentiated on the basis of various physical and chemical properties.

Metals are the elements they are generally hard as strong metallic bond exists between the atom.

While the elements 4,5,6 or 7 eletrons in their otermost shell are known as non-metals.

Answer 2

Answer:

Explanation:

Metals:-

:- metals have shining surface.

:- they are generally hard.( Except sodium, lithium and potassium)

:- Exits as solids.( Except Mercury)

:- Metals can be beaten into thin sheets.( Gold and silver is the most malleable)

:- metals can be drawn into thin wires.

:- Metals are good conductors of heat and electricity.( Except lead and Mercury)

:- generally have high density and high melting point.( Except sodium and potassium)

:- metals produce a sound on striking a hard surface.

:- metallic oxides are basic in nature.

Non - metals

:- they do not have shining surface (except iodine)

:- generally soft.( Except diamond)

:- exist as solids and gaseous.( Except bromine- liquid state)

:- non- metals are non- malleable.

:- they are non- ductile.

:- Non- metals are poor conductors of heat and electricity.( Except graphite)

:- have low density and low melting point.

:- they are not sonorous

:- non - metallic oxides are acidic in nature.
