Question

The total number of atomic orbitals in fourth energy level of an atom is?

• A. $4$
• B. $8$
• C. $16$
• D. $32$

Answer 1

The correct option is C $16$

Solution:-

Number of atomic orbitals in an orbit $=n^2$

where, n = energy level

$\therefore$ Number of atomic orbitals in fourth energy level $=4^2=16$

Hence, the total number of atomic orbitals in fourth energy level of an atom is 16.
