The principal quantum number defines the general value of the electronic energy. The angular momentum quantum number determines the shape of the orbital. And the magnetic quantum number specifies orientation of the orbital in space, as can be seen in Figure \(\PageIndex{3}\).

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.
Quantum numbers are a way of describing the orbitals and electrons contained in an atom. There are 4 unique quantum numbers for every electron in an atom. 1) Principal quantum number (n) which defines the electrons distance from the nucleus.
Quantum numbers. Every electron localized in an atom can be described by four quantum numbers. The Pauli Exclusion Principle tells us that no two electrons can share the exact same set of quantum numbers. Principal quantum number. The principle quantum number, n, represents the energy level of the electron, much like the n used in the Bohr model.
Quantum numbers tell us where an atom's electrons can be found. Electrons share the space around nuclei. Quantum numbers tell us where the electrons are and how much energy they have. Each electron in an atom has a unique set of four quantum numbers.
Principal Quantum Numbers (n) and the Periodic Table. Each electron shell has a principal quantum number n. = 1 is the 1st shell, = 2 is the 2nd shell, = 3 is the 3rd shell, etc.
2 Quantum Numbers and Atomic Orbitals Each electron in an atom is described by four different quantum numbers (n, l, m l, & m s) 1.Principal Quantum Number (n): Specifies the energy of an electron and the size of the orbital. All orbitals that have the same value of n are said to be in the same shell (level). n takes the values of 1, 2, 3 ...
