Question

An electron in an atom moves from the second energy level (n=2) to the third energy level (n=3). Which of the following is true?

a) Energy is destroyed in the transition
b) Energy is absorbed in the transition
c) Energy is released in the transition
d) Energy is created in the transition

Answer 1

Energy is released in the transition.

Step-by-step explanation:

The correct answer is c) Energy is released in the transition.

When an electron moves from a higher energy level to a lower energy level, it releases energy in the form of a photon. This is known as an emission or de-excitation process. The energy of the released photon is equal to the difference in energy between the two energy levels.

In this case, the electron is moving from the second energy level (n=2) to the third energy level (n=3), so energy is released during this transition.
