<u>Answer</u>:
According to Bohr's theory, an electron's path around the nucleus defines its
energy level.
<u>Explanation</u>:
It the certain energy by which the electrons have occupied there place in the orbitals. They can also be moved to the higher energy level by taking the energy from the surrounding. The emission of light can be seen when the electron falls from the higher energy state to the lower state. The orbital that is close to the atomic centre having the lowest energy level and the one that is found to be far away from the atomic centre has the highest energy level.
