Which of the following statements concerning the quantum numbers are correct?

(i) Angular quantum number determines the threedimensional shape of the orbital.

(ii) The principal quantum number determines the orientation and energy of the orbital.

(iii) Magnetic quantum number determines the size of the orbital.

(iv) Spin quantum number of an electron determines the orientation of the spin of electron relative to the chosen axis.

The correct set of option is

View answer and explanation

Correct option: B

(i) and (iv)

Option B is correct because the angular quantum number determines the shape of the orbital, and the spin quantum number determines the orientation of the electron's spin.
