Question

According to Bohr, when an electron jumps from one shell to another:

• A. if it gains energy, it moves away from the nucleus
• B. when it gains energy it moves towards the nucleus
• C. it emits energy in the form of radiations when it moves from higher energy level to lower energy level
• D. it always gains energy in the form of light

Answer 1

Answer: (A), (C)

if it gains energy, it moves away from the nucleus
it emits energy in the form of radiations when it moves from higher energy level to lower energy level

According to Bohr, when an electron gains energy, it moves away from nucleus (from low energy state to a higher energy state) . When an electron falls from higher energy state to lower energy state, it emits energy in form of radiations.
