$\huge{Hello Friend}$

The answer of u r question is..✌️✌️

✖️Explain principal quantum number✖️

Ans:✍️✍️✍️✍️✍️✍️✍️

The Principal Quantum Number explains about the size and energy of the orbitals this orbitals are called energy levels of shells it is represented by l m have only non zero positive integers values like 123 extra SN increases the cell becomes larger and the electrons in those orbitals are further from the nucleus as an increasing energy of the cell also increases the number of electrons in a shell is limited to and Square..

Answer 2

$\underline{\large\bf{\mathfrak{Hello!}}}$

⭐ Principal quantum number(n) ⭐

This quantum number tells about:

1) The shell to which the electron belongs.
Ex: Electron with principle quantum number n = 2 belongs to second shell around the nucleus.

2) Specifies the size of the shell.
As the principal quantum number increases, the size of the shell increases, therefore now the electron will be away from nucleus as (n) is increased.

3) Energy of the shell
Larger is the distance of the shell in which electron is present, higher will be it's energy.

4) Maximum number of electrons that a shell can accomodate is 2n².

It always have positive values like 1, 2, 3... etc.
