Question
How many numbers of orbitals does the third shell consists of:
- 5
- 9
- 10
- 3
Hint:
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.
