The elements of group IA provide a colour to the flame of Bunsen burner due to

A

Low ionization potential

B

Low melting point

C

Softness

D

Presence of one electron in the outermost orbit

Text Solution

Verified by Experts

The correct Answer is:
A
Elements of group IA have low ionization energy, so the electron in the outermost orbit can easily go to excited state. On reverting back to initial state, it emits energy as visible light.
