The possible state for an electron of an atom that is proportional to its distance to the nucleus. true or false

The given statement is true.

Explanation:

Energy level is the possible state for an electron of an atom that is proportional to its distance to the nucleus.

When the electron makes transition from excited state to the ground state then the energy will be released by the electron in this case resulting in lower energy level. The electron will orbit nearer to the nucleus.

When the electron makes transition from ground state to the excited state then the energy will be absorbed or gained by the electron in this case resulting in higher energy level. The electron will orbit further from the nucleus.

Therefore, the given statement is true.
