Detailed Solution

(a) Azimuthal quantum number 'l' is also known as orbital angular momentum or subsidiary quantum number. It determines three dimensional shape of the orbital.(b) The principal quantum number determines the size of the orbital.(c) Magneitc quantum number determines the orientation of the electron cloud in a subshell.(d) An electron spins around its own axis, much in a similar way as earth spins around its own axis while revolving around the sun. In other words, an electron has, besides charge and mass, intrinsic spin angular quantum number.
