What does the negative electronic energy (negative sign for all values of energy) for hydrogen atom means?

A

The energy of an electron in the atom is lower than the energy of a free electron at rest which is taken as zero.

B

When the electron is free from the influence of nucleus it has a negative value which becomes more negative.

C

When the electron is attracted by the nucleus the energy is absorbed which means a negative value.

D

Energy is released by hydrogen atom in ground state.
