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

(i) The angular quantum number determines the three-dimensional shape of the orbital.

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

(iii) The magnetic quantum number determines the size of the orbital.

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

 

 

Correct Answers:

(i) The angular quantum number determines the three-dimensional shape of the orbital

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

Explanation: Angular quantum number determines the three dimensional shape of the orbital and the electron spin quantum number determines the spin orientation of electron relative to its chosen axis.
