What does the negative electronic energy (negative sign for all values of energy) for hydrogen atom means?
- The energy of an electron in the atom is lower than the energy of a free electron at rest which is taken as zero.
- When the electron is free from the influence of nucleus it has a negative value which becomes more negative.
- When the electron is attracted by the nucleus the energy is absorbed which means a negative value.
- Energy is released by hydrogen atom in ground state.
Answer
(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.
