What is Hund's rule and what is its purpose?

Hund's Rule states that due to electron repulsion, electrons in the same subshell occupy different orbitals with parallel spin. It is used, along with the Pauli Exclusion Principle to obtain ground state electron configurations.

Hund’s Rule basically states that, due to electron repulsion, each orbital in a sub shell is occupied by a single electron before any electrons within that orbital are paired. It also explains that each of the single electrons have the same spin. The rule helps us to figure out electron configuration and just serves as a general rule to know in chemistry.

I like to think Hund's Rule as a school bus. When you enter a bus, you would rather take the empty seat than sit next to someone else. This can apply to electrons in each subshell of an orbital. The subshells need to each have 1 electron before there can be two electron in each subshell.

Hund's Rule says that every orbital in a sublevel must be occupied by one electron before any orbital is occupied by two electrons, and all of these lone electrons have the same spin.

Hund's Rule describes the tendency of electrons to want to be in the lowest state of energy, which means minimizing any forces of repulsion. Electrons thus will occupy empty orbitals before occupying an orbital that is occupied by another electron. This rule helps us determine the electron configuration of different atoms.
