Question

Select the correct answer.

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?
OA.
The electron releases energy in the form of light.
OB.
The electron absorbs energy in the form of light.
The electron retains its energy without any change.
Oc.
OD.
The electron transfers its energy to other electrons.

Answer 1

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

Step-by-step explanation:

When absorbing energy, an electron starts moving to an excited state (unstable state) different from normal "ground state" (stable state). Since the electron is in unstable or excited state, it tends to change 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.
