The quantum number which determines the shape of the subshell is:
Show Hint
- Principal quantum number
- Magnetic quantum number
- Azimuthal quantum number
- Spin quantum number
- Principal and magnetic quantum number
The Correct Option is C
Solution and Explanation
Step 1: The azimuthal quantum number \( l \) determines the shape of the subshell.
Step 2: For example, \( l = 0 \) corresponds to an \( s \)-orbital (spherical), \( l = 1 \) corresponds to a \( p \)-orbital (dumbbell-shaped), and so on.
Step 3: Thus, the shape of the subshell is determined by the azimuthal quantum number.
