Question

what is quantum number and explain it's type​

Answer 1

Answer:

Quantum number is a value, which is used to describe the energy available in atoms and molecules. Moreover, an electron within an ion or an atom has four such numbers to portray its energy state. Additionally, it yields clarifications to the wave equation for hydrogen atoms by Schrodinger. These four quantum numbers are –

• n is the principal quantum number, and it expresses the energy levels.

• ℓ is azimuthal or angular momentum quantum number; it describes the subshell.

• mℓ or m is a magnetic quantum number which expresses the orbital of a subshell.

• ms or s is the spin quantum number expressing the spin.

Furthermore, every electron in an atom has a set of unique quantum numbers. According to the ‘Pauli exclusion principle’, these four quantum numbers and their combination cannot be the same in two electrons.  

Additionally, these quantum numbers are crucial, as they are used to comprehend the electron configuration of an atom. Besides, they also give an idea of the possible location of an atom’s electrons. Moreover, the significance of quantum number is that it is useful to gather information on characteristics of atoms like its radius, and ionisation energy.

Answer 2

Explanation:

The set of numbers used to describe the position and energy of the electron in an atom are called quantum numbers. There are four quantum numbers, namely, principal, azimuthal, magnetic and spin quantum numbers. The values of the conserved quantities of a quantum system are given by quantum numbers.
