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.
14 Αυγ 2024 · Quantum numbers are important because they can be used to determine the electron configuration of an atom and the probable location of the atom's electrons. Quantum numbers are also used to understand other characteristics of atoms, such as ionization energy and the atomic radius.
If the quantum numbers of an ion are given, how can we identify this ion by its quantum numbers? For example : n = 3; l l = 2; ml m l = 0; m s s = + ½.
A comparison of the dimensions of atoms or ions that have the same number of electrons but different nuclear charges, called an isoelectronic series, shows a clear correlation between increasing nuclear charge and decreasing size.

Table of contents: A quick review of the nuclear structure. The electron configuration. What is electron shielding? What is the effective nuclear charge?
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.
