Question

what is quantum number give their names

Answer 1

it will help u.........;)
principal quantum no
azimuthal quantum no
magnetic quantum no
spin quantum no

Answer 2

A total of four quantum numbers are used to describe completely the movement and trajectories of each electron within an atom. The combination of all quantum numbers of all electrons in an atom is described by a wave function that complies with the Schrödinger equation. Each electron in an atom has a unique set of quantum numbers; according to the Pauli Exclusion Principle, no two electrons can share the same combination of four quantum numbers. 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 determine other characteristics of atoms, such as ionization energy and the atomic radius.
The names of quantum no.s are:
the principal quantum no.
the orbital angular quantum no.
the magnetic quantum no.
the electron spin quantum no.
