In Bohr's atomic theory, when an electron moves from one energy level to another energy level more distant from the nucleus: Select one: a. Energy is emitted. b. Energy is absorbed. c. No change in energy occurs d. Light is emitted. e. None of these.

(b)

Explanation:

Energy levels farther from the nucleus represent higher energies. Therefore, in order for the electrons to reach these levels, they must absorb additional energies first before they can make the jump.
