Question

Evaluate the scenario.

An electron in the energy level closest to the nucleus absorbs a photon.


Which of the answer choices best describes what will happen next?


The electron will move from a higher energy level to a lower energy level.

The electron will move from the first energy level to the third energy level.

The electron will move from a lower energy level to a higher energy level.

The electron will move from the first energy level to the second energy level.

Answer 1

The electron will move from the first energy level to the second energy level.

The energy level closest to the nucleus is the first energy level, and when an electron absorbs a photon, it absorbs the energy in the photon. This absorption causes the electron to move from the first to second energy level.
