Question

Which of the following best describes how an electron moves when it absorbs or releases exact amounts of energy?

A.The electron moves to the ground state.
B.The electron moves between orbital levels. C.The electron moves to bond with other electrons. D.The electron moves beyond ionization potential.

Answer 1

B.The electron moves between orbital levels.

Answer 2

Answer: The correct option is B.

Step-by-step explanation: As the electron moves from lower energy level to higher energy level, it absorbs some amount of energy. When the electron returns back from this higher energy level to the lower energy level, it emits the exact amount of energy it has absorbed.

As every orbital has its characteristic energy value, whenever electrons absorb or emit energy, they move to different energy level that is they occupy different orbitals and hence we can say that the electron moves between orbital levels.
