Question

What happens when an electron absorbs energy? A. The electron moves from a lower energy orbital to a higher energy orbital. B. The electron falls into the nucleus. C. The electron moves from a higher energy orbital to a lower energy orbital. D. The electron loses its charge.

Answer 1

A. The electron moves from a lower to a higher energy orbital

Answer 2

Answer:  A. The electron moves from a lower energy orbital to a higher energy orbital.

Explanation:  When a sufficient amount of energy is provided to the electron, it gets excited from a lower enrgy orbital to the higher energy orbital.

In moving from lower enrgy orbital to the higher one, it absorb some molecular energy. And thus when it comes back to the ground state , it will release this energy in the form of light and thus color appears.
