Why does the energy of the electron in a hydrogen atom have a negative sign for all possible orbits in Bohr's model?

Options

  1. ABecause electrons are negatively charged particles.
  2. BBecause the nucleus is positively charged.
  3. CBecause the energy of the electron is always lower than that of a free electron at rest.
  4. DBecause the energy of the electron is always higher than that of a free electron at rest.

Correct answer

C. Because the energy of the electron is always lower than that of a free electron at rest.

Step-by-step solution

The negative sign of the energy indicates that the energy of the electron in the atom is lower than the energy of a free electron at rest.
