Solution

The correct option is A size of the orbital
The principal quantum number 'n' represents orbit number hence, determine the size of orbitals. The principal quantum numbers are represented by the letters 'K, L, M, N' or equal to 1, 2, 3, 4, etc.

The maximum number of electrons that can accommodate in a principal energy shell is given by $2 n^{2} .$ .
