Principal quantum number (n)
The first quantum number, defining the energy level or shell occupied by an electron.Proteins
Proteins
Long-chain polypeptides with high molecular weights.Proton (H+)
Proton (H+)
A subatomic particle that carries a single positive charge and has a mass defined as one or as the
hydrogen ion, H+, which is simply a hydrogen nucleus, consisting of one proton. These species are
considered to be equivalent.

Quantum number
A number used to describe the energy levels available to electrons. The state of any electron is
described by four quantum numbers. See Principal quantum number; Azimuthal quantum number;
Magnetic quantum number; Spin quantum number.
