How many electrons can exist with the principal quantum number’s...
The principal quantum number (n) represents the energy level or shell of an electron in an atom. The maximum number of electrons that can exist in a particular energy level is given by the formula 2n^2.
For example:
- When n = 1, the maximum number of electrons is 2(1)^2 = 2.
- When n = 2, the maximum number of electrons is 2(2)^2 = 8.
- When n = 3, the maximum number of electrons is 2(3)^2 = 18.
- When n = 4, the maximum number of electrons is 2(4)^2 = 32.
So, the number of electrons that can exist with a specific principal quantum number (n) can be found using the formula 2n^2.

How many electrons can exist with the principal quantum number’s...
The number of orbitals within an orbit is n2. But as each orbital can accommodate 2 electrons, the number of electrons that can exist with the “n” as the principal quantum number is 2n2. So here 2n2 = 2(4)2 = 2(16) = 32.
