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

Options

A. Angular quantum number determines the three dimensional shape of the orbital
B. The principal quantum number determines the orientation and energy of the orbital
C. Magnetic quantum number determ ines the size of the orbital
D. Spin quantum number of an electron determines the orientation of the spin of electron relative to the choses axis.

Explanation

(a) Azimulthal quantum number 'l' is also known as orbtial angualr momentum or subsidiary quantum number it determines the oreintation and energy of the orbtial
(c) Magnetic quantum number determines the size of the orbital
(d) Spin quantum number of an electron determines the orientation of the spin of electron relative to the choosen axis.
