Question

hey guys:-.
tell me about quantum numbers in detail !

Answer 1

Hey mate here is your answer》》

All electrons have four quantum numbers which describe the location of electrons in the electron cloud of an atom. The principle quantum number (n) describes the size of the orbital the electron is in. The angular momentum quantum number (l) describes the shape of the orbital. The magnetic quantum number (ml) describes the orientation of the orbital in space while the electron spin number (ms) describes the direction that the electron spins on its own axis.

Hope this answer will help you..《《

Answer 2

there are 4 types of quantum no.s
they are as follows--
Principal Quantum Number
Angular Quantum Number
Magnetic Quantum Number
Spin Quantum Number

Principal Quantum Number

The first is the principal quantum number (n) which describes the main energy level and size of an orbital i.e. the distance of the orbital from the nucleus. It is also referred to as a shell and the number of orbital in a shell and is given by n2.

Angular Quantum Number

The second is named as the azimuthal quantum number and also known as orbital angular momentum is denoted by l. It describes the shape and the type of orbital. There are 4 types of orbitals i.e. s, p, d, and f. The value of l ranges from 0 to n-1.

Magnetic Quantum Number

The third is the magnetic quantum number which is denoted by m. This describes the spatial orientation of the orbital. The s-orbital has only 1 possible position, p-orbital has 3 possible positions, d-orbital has 5 possible positions and f-orbital has 7 possible positions. The number of possible positions in an orbital is given as 2l + 1.

Spin Quantum Number

The fourth is the spin quantum number (ms). It deals with the spin of an electron in a subshell about an axis.
