What is the maximum number of electrons the n = 4 shell can contain?

The number of electrons in n = 4 energy level will be 32.

Explanation:

The total number of electrons that are contained in any energy level is calculated by using the formula of where n = principle quantum number = 1, 2, 3, 4, 5 ...

We are given:

Principle quantum number of the value, n = 4

Putting this in above equation, we get:

Hence, the number of electrons in n = 4 energy level will be 32.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
