Question

What are the four significance of Quantum number ?

Answer 1

Answer:The quantum numbers are the address of an electron in an atom.

The four quantum numbers are Principal quantum number (n), Azimuthal quantum number (l), Magnetic quantum number (m), Spin quantum number (s)

Explanation:

Principal quantum number or n gives in which shell(orbit) the electron revolving(also size and energy)

Azimuthal quantum number or l gives the idea about in which subshell electron is present

Magnetic quantum number or m gives the idea about in which orbital the electron present.

Spin quantum number or s describe the spinning of electron the two values are +1/2 and -1/2 but that doesn't mean clockwise and anti-clock wise spin
