Chemistry - GENERAL CHEMISTRY Question with Solution | TestHub

In $n{p}^2$ configuration two electrons in the same orbital have a higher energy than two electrons in different orbitals from same subshell.

The multiplicity is the number of unpaired electron with parallel spin plus 1.

In the ground state of the atoms, the orbitals are filled in order of their decreasing energies.

The energy of an electron in a hydrogen atom is determined solely by its principal quantum number.
