Question

How many numbers of orbitals does the third shell consists of:

  1. 5
  2. 9
  3. 10
  4. 3

hintHint:

The 3rd shell has 9 orbitals which is the combination of 3s, 3p, and 3d orbitals.

The correct answer is: 9


    • The electrons are distributed in shells in specific combinations.
    • The 1st shell has only s orbitals, the 2nd shell has s and p orbitals and the 3rd shell has s,p, and d orbitals. 
    • The third shell has 3s, 3p, and 3d orbitals.
    • So the number of orbitals present in the 3rd shell is 9.
