Description: We all know that the electrons revolve around the nucleus but do you know how to distribute electrons in different orbits? Let's dive into this video.

Question

A hydrogen atom has the main energy levels (shells) shown in the diagram below. $n$ refers to the shell number. This is the Bohr model of the atom.

List these electron transitions in order of increasing wavelength of light absorbed or emitted:

$n = 1$ to $n = 2$
$n = 3$ to $n = 2$
$n = 2$ to $n = 4$
$n = 3$ to $n = 1$

Accepted Answer

Niels Bohr ( $1885 — 1962$ ) suggested electrons occupied orbits around the nucleus, and that the volume of the space occupied by electrons around the nucleus depended on the energy of the electrons. These possible locations for electrons at different distances from the nucleus are also called shells or main energy levels. When an electron absorbs a specific, fixed amount of energy (called a quantum) it is promoted to a different orbit. The same amount of energy is re-emitted as electromagnetic radiation when the electron drops back to its lower energy level. The electron transitions in order of an increasing wavelength of light absorbed or emitted are as follows:

$n = 3$ to $n = 2$ $n = 3$ $n = 2$ to $n = 4$ $n = 2$ $n = 1$ to $n = 2$ $<$ $n = 3$ to $n = 1$
