Explain Quantum Numbers......................
Answers
A quantum number is a value that is used when describing the energy levels available to atoms and molecules. An electron in an atom or ion has four quantum numbers to describe its state and yield solutions to the Schrödinger wave equation for the hydrogen atom.

Step-by-step explanation: Hey Mate This Might Help You!!!!
Quantum numbers describe values of conserved quantities in the dynamics of a quantum system. In the case of electrons, the quantum numbers can be defined as "the sets of numerical values which give acceptable solutions to the Schrödinger wave equation for the hydrogen atom".
There are a total of four quantum numbers: the principal quantum number (n), the orbital angular momentum quantum number (l), the magnetic quantum number (ml), and the electron spin quantum number (ms).
The principal quantum number just indicates the size of the orbital or energy level, the angular momentum quantum number indicates the shape of the orbital, the magnetic quantum number indicates the orientation or position of the orbital, and the spin quantum number indicates the spin of the electron.
In Chemistry:-
Orbitals within a shell are divided into subshells that have the same value of the angular quantum number. Chemists describe the shell and subshell in which an orbital belongs with a two-character code such as 2p or 4f. The first character indicates the shell (n = 2 or n = 4).
