Sodium is strongly metallic, while chlorine is strongly non-metallic -explain.

Text Solution

Verified by Experts

`rarr` Sodium is an alkali and it is present in group `-1` and it has the ability to lose the valency electron readily.
`rarr` It has high electropositive nature. So it has metallic nature.
`rarr` Chlorine is a halogen and it is placed in Group `-17` and it has the ability to gain the electron readily.
`rarr` it has high electronegative nature. So it has non metallic nature.
