What is Bohr Model? (See Bohr Diagrams of all 118 Elements)

What is a Bohr model?
Bohr model is a structural model in which the negatively charged electrons revolve around the positively charged nucleus. This is similar to the planets revolving around the sun, except that the orbits are non-planar.

The electrons move in a fixed orbits (shells) and each orbit has a fixed energy.
Each orbit (or shell) can hold a certain number of electrons.

Here is a simple table showing the number of electrons that can be accommodated in each shell.

Number of electrons in each shell;

Orbit / Shell (n)	Maximum no. of electrons this orbit can hold
K shell, n = 1	2
L shell, n = 2	8
M shell, n = 3	18
N shell, n = 4	32
.	.
.	.

Thus, 1st shell can hold 2 electrons, 2nd shell can hold 8 electrons, 3rd shell can hold 18 electrons, 4th shell can hold 32 electrons, and so on.
