Maximum number of orbitals is given shell identified by the principal quantum number `n` is equak to

Options

A. `n`
B. `n^(2)`
C. `2n^(2)`
D. `2n`

Answer

B

Explanation

All the orbitals of a given value of `n` consitute a single shell of atom. With the increase in the value of `n`, the number of allowed orbitals increases and is given by `n^(2)`.
