The energy of the electron in a hydrogen...

The energy of the electron in a hydrogen atom has a negative sign for all possible orbits because

A

when the electron is attracted by the nucleus and is present in orbit n, the energy is emitted and its energy is lowered.

B

when the electron is attracted by the nucleus and is present in orbit n, the energy is absorbed and its energy is increased.

C

when the electron is repelled by the nucleus, the energy is released and its energy is lowered.

D

none of these.
