Which quantum number determines the shape of an atomic orbital?
- A.Principal quantum number
- B.Azimuthal quantum number
- C.Magnetic quantum number
- D.Spin quantum number
Show correct answer & step-by-step solution
Correct answer: B — Azimuthal quantum number
Solution
- The principal quantum number determines the size and energy.
- The azimuthal quantum number determines the shape of the orbital.
- The magnetic quantum number determines the orientation.
- The spin quantum number determines the electron spin.
- Hence the answer is (B).
