In quantum mechanics, the principal quantum number (symbolized n) is one of four quantum numbers assigned to each electron in an atom to describe that electron's state. Its values are natural numbers (from one) making it a discrete variable.
11 Αυγ 2017 · The original three quantum numbers describe properties of the electron cloud (orbital). Later, a fourth quantum number was added, the measurement of spin. All four quantum numbers are required when applying another important part of quantum physics, the Pauli Exclusion Principle.
Some quantum numbers, such as intrinsic spin, are related to fundamental classifications of subatomic particles, and they obey laws that will give us further insight into the substructure of matter and its interactions.
The quantum numbers are parameters that describe the distribution of electrons in the atom, and therefore its fundamental nature. They are: 1. PRINCIPAL QUANTUM NUMBER (n) - Represents the main energy level, or shell, occupied by an electron. It is always a positive integer, that is n = 1, 2, 3 ... 2.
A set of the four quantum numbers describes the unique properties of one specific electron in an atom. Since each set is unique, they serve as a way of uniquely naming individual electrons (i.e. a kind of coordinate system).
In physics, a quantum (pl.: quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. Quantum is a discrete quantity of energy proportional in magnitude to the frequency of the radiation it represents.
