The correct answer is statement that a fixed amount of energy was absorbed.
Explanation:
In an atom, the electrons prevail in distinct energy levels. The electrons present in an atom are confined to a particular level of energy, which is located at different distances from the nucleus. The electrons, which are in the highest energy level are known as valence electrons. Inside every energy level lies a space volume where particular electrons are situated.
The energy is absorbed by the atom when an electron moves to a higher energy level from a lower energy level, and the energy is discharged when an electron moves to a lower energy level from a higher energy level in the form of light.
