Why do halogens exhibit different colors?
Options
- ADue to their melting points
- BDue to the excitation of outer electrons
- CDue to their atomic masses
- DDue to the number of valence electrons
Correct answer
B. Due to the excitation of outer electrons
Step-by-step solution
Halogens exhibit different colors due to the excitation of their outer electrons to higher energy levels, which results in the absorption of radiations in the visible region.
