What is the maximum number of electrons that can be accommodated in an atom in which the highest principal quantum number is 4?

(c) : n = 3, l = 0 represents 3s orbital n = 3, l = 1 represents 3p orbital n = 3, l = 2 represents 3d orbital n = 4, l...

(c) two extra neutrons and no extra electron

5-electrons.......

1 electrons....

It shows the distance ofelectron from nucleus. It refers as principal energy level. The possible values of (n) are 1 to 7. (As per existing elements) 

(a) Magnetic quantum number represents the number of orbitals present in the sub-shell magnetic quantum number about the orientation of the orbital.

(c) The energy of a shell.

The correct answer is (D) 8

(B) The maximum number of electrons is 36.
