Question

Light is released when an excited electron moves from higher energy level back down to its lower, more stable energy level. The resulting spectrum is a(n) _____ spectrum. A) emission B) absorption C) excitation D) higher energy

Answer 1

A0 emission as there is an increase in energy

Answer 2

Answer: Option (A) 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.

On the other hand, absorption of energy occurs when an electron moves from lower to higher energy level.

Thus, we can conclude that light is released when an excited electron moves from higher energy level back down to its lower, more stable energy level. The resulting spectrum is an emission.
