Question

Consider an atom that has an electron in an excited state. The electron falls to a lower energy level. What effect does that have on the electron? A. The electron releases energy in the form of light. B. The electron absorbs energy in the form of light. C. The electron retains its energy without any change. D. The electron transfers its energy to other electrons.

Answer 1

B. As the electron falls to a lower energy level the energy is absorbed .

Answer 2

Answer: The correct option is A.

Explanation: An electron is in the upper energy state which is the unstable state.

$Energy\propto \frac{1}{Stability}$

As the energy and stability follow inverse relation, higher energy means lower stability.

So, when an electron falls from upper energy level to lower energy level in order to gain stability, it releases some amount of energy in the form of light.

Hence, the correct option will be : the electron releases energy in the form of light.
