Hope answer is helpful.
plz make my answer as brainalist one .

Answer 2

Here is ur answer.....
1. In an atom, the electrons revolve around the nucleus in certain definite circular paths called orbits, or shells.

2.Each shell or orbit corresponds to a definite energy. Therefore, these circular orbits are also known as energy levels or energy shells.

3.The electrons present in an atom can move from a lower energy level to a level of higher energy by absorbing the appropriate energy. Similarly, an electron can jump from a higher energy level to a lower energy level by losing the appropriate energy.

4.The orbits corresponding to n = 1,2,3,4…..etc., are also designated as K,L,M,N……….etc., shells. When the electron is in the lowest energy level, it is said to be in the ground state.
