Question

halogen are colourful ?why ?

Answer 1

Almost all halogens are coloured. This is because halogens absorb radiations in the visible region. This results in the excitation of valence electrons to a higher energy region.

Answer 2

Halogens are colourful because

• Halogens absorb radiations in the visible region.

• This results in the excitation of valence electrons to a higher energy region.

• Since the amount of energy required for excitation differs for each halogen, each halogen displays a different colour.
