Question

Out of principal, angular, magnetic and spin quantum number, which quantum number determines the?

(i) Shape of the orbital 

(ii) Number of orbitals in an orbit 

(iii) Size of the orbital 

(iv) Spin orientation of the electron

Answer 1

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

(ii) Magnetic quantum number determines the number of orbitals in an orbit. 

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

(iv) Spin quantum number determines the spin orientation of the electron.
