Question

What is quantum number?
and What are the types
of quantum number and
explain it ?
​

Answer 1

Answer:

Quantum numbers

     The set of numbers used to describe the position and energy of the electron in an atom are called quantum numbers

Types  of quantum number

    There are four types of quantum number

they are

• Principal quantum number
• Azimuthal quantum number
• Magnetic quantum number
• Spin quantum number

Principal quantum numbers

    The principal quantum number, n, describes the energy of an electron and the most probable distance of the electron from the nucleus. In other words, it  represents the orbit number.

Azimuthal quantum number

    Azimuthal quantum number is a quantum that determines its orbital angular momentum and describes the shape of the orbital

Magnetic quantum number

    Magnetic quantum number specifies the orientation in space of an orbital of a given energy (n) and shape (l). This number divides the subshell into individual orbitals which hold the electrons; there are 2l+1 orbitals in each subshell

Spin quantum number

    spin quantum number describes the intrinsic angular momentum of a given particle. It also represents the direction of momentum
