Question

Explain magnetic quantum number?

Answer 1

Quantum numbers

• The energy levels that are available to atoms and molecules are described by a quantum number.
• In order to explain its state and provide solutions to the Schrödinger wave equation for the hydrogen atom, an electron in an atom or ion has four quantum numbers.
• The four quantum numbers are as follows:

1. Principal quantum number $\left(n\right)$
2. Azimuthal quantum number $\left(l\right)$
3. Spin quantum number $\left(s\right)$
4. Magnetic quantum number $\left(m_l\right)$

Magnetic quantum number

• One of the four quantum numbers that describe an electron's position in relation to the nucleus is its magnetic quantum number.
• The number of orbitals and their orientation within a particular sub-shell is principally determined by the magnetic quantum number.
• It is dependent on the azimuthal quantum number, also referred to as the azimuthal orbital angular momentum quantum number.
