(a) The angular momentum 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 determines the size of the orbital.
(d). Spin quantum number of an electron determines the orientation of the spin of electron relative to the chosen axis.
Which pair of quantum numbers determine the energy of an electron in an orbital?
In Hydrogen, the energy of an electron is determined solely by principal quantum number (n).
