Answer 1

Answer:

Hii

But this is not the only effect we have to take into account. Within each shell, as the value of l increases, the electrons

Answer 2

⚠️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.
