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

Answer:

Correct answer is A

Explanation:

i did the test :)

Answer 2

On absorbing energy, an electron moves to an excited state (unstable state) from its ground state (stable state).  Since the electron is in unstable state so it tends to rearrange itself to return to its lowest energy state.  On returning to lowest energy state which is stable, it releases energy in the form of light.

Hence, option A that is the electron releases energy in the form of light on falling to lower energy state from excite state.
