Question

explain quantum number and its types​

Answer 1

Answer:

Quantum Number Values :

According to the Pauli exclusion principle, no two electrons in an atom can have the same set of quantum numbers. Each quantum number is represented by either a half-integer or integer value.

--The principal quantum number is an integer that is the number of the electron's shell. The value is 1 or higher (never 0 or negative).

--The angular momentum quantum number is an integer that is the value of the electron's orbital (for example, s=0, p=1). ℓ is greater than or equal to zero and less than or equal to n-1.

--The magnetic quantum number is the orientation of the orbital with integer values ranging from -ℓ to ℓ. So, for the p orbital, where ℓ=1, m could have values of -1, 0, 1.

--The spin quantum number is a half-integer value that is either -1/2 (called "spin down") or 1/2 (called "spin up").
