An electron in a hydrogen atom moves from level 3 to level 1. In a second hydrogen atom, an electron drops from level 2 to level 1. Which statement describes the most likely result?

The higher or further away an electron orbital is from the nucleus of an atom, the higher its energy levels. Therefore, the electron at orbital 3 has higher energy levels than that of energy levels 2 and 1. That of energy level 2 has higher energy than that of level 1. According to the Bohr principle, electrons can make a quantum jumps across energy levels.

║Δ E║ = E (final) – E (initial) = hv

Whereby;

E – energy level

h – plank’s constant

v - frequency of the electromagnetic radiation

When an electron jumps from a lower to higher energy level, it absorbs a specific wavelength of electromagnetic radiation equivalent to this quantum leap. When the electron jumps from a higher to a lower energy level, it releases electromagnetic radiation of equivalent energy difference between the energy levels. These present unique signatures that are used to identify atoms of a particular element.
