Question

Maximum number of electrons in a principal sheel is

Answer 1

The maximum number of electrons in a principal shell is

$2 {n}^{2}$

Where n is the principal shell number

Answer 2

Answer:

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.
