Question

Which of the following occurs when an electron moves from a higher energy shell to a lower energy shell?

Answer 1

Answer: Option (C) is the correct answer.

Explanation:

When energy is supplied to an electron then on absorption of energy it tends to move from a lower energy level to higher energy level.

And, when this electron moves from higher energy level to lower energy level then excess of energy absorbed by it is released in the form of visible light or radiation.

This emission of energy is also responsible for imparting color to a compound.

Thus, we can conclude that energy is released in the form of radiation occurs when an electron moves from a higher energy shell to a lower energy shell.

Answer 2

The answer would be C: energy is released to form radiation.
