Question

The energy of each orbit is:

• A. fixed
• B. keeps changing
• C. sometimes fixed and sometimes changes
• D. energy is determined by momentum

Answer 1

The correct option is A fixed

Bohr’s model describes that electrons travel in separate orbits around the nucleus. Each orbit is associated with a fixed amount of energy. The electrons present in these shells, neither lose nor gain energy until some external force is applied to it. Thus, they maintain their position. The shells have a fixed amount of energy.
