Answer 1

Answer:

When an atom gains or loses energy, the  energy of an electron can change.

An electron in an atom can move from one  energy level to another when the atom gains  or loses energy.

Answer 2

Answer: Option (c) is the correct answer.

Explanation:

When energy is supplied to an electron then upon 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 when an electron loses its energy then it may drop to a lower energy level.
