Principal Quantum Number Chart. A value of the azimuthal quantum number can indicate either an s, p, d, or f subshell which vary in shape. Specifies the energy of an electron and the size of the orbital (the distance from the nucleus of the peak in a radial probability distribution plot).
Each one is a particular factor in an equation describing a property of the electron. The following list is a condensation of some of the most useful information relevant to quantum numbers and electronic structure. We usually say that n labels which shellthat the electron occupies.
There are four major subshells: s, p, d, and f, whose names derive from spectroscopic descriptions of sharp, principal, diffuse, and fundamental.
There are four quantum numbers: n, ℓ, m ℓ, and m s.
The first quantum number describes the electron shell, or energy level, of an atom. The principal quantum number describes the electron shell, or energy level, of an electron. The principal quantum number is the quantum number denoted by n and which indirectly describes the size of the
electron orbital.
