Question

(i) State Hund’s Rule of maximum multiplicity.

(ii) How many electrons in an atom can have the following quantum numbers?

(a) n=4 :ms=-1/2 (b) n=3, l=0

(iii) Show that the circumference of the Bohr orbit for the hydrogen atom is an

integral multiple of the de Broglie wavelength associated with the electron revolving

around the orbit.​

Answer 1

Answer:

Hund's Rule of Maximum Multiplicity rule states that for a given electron configuration, the term with maximum multiplicity falls lowest in energy. According to this rule electron pairing in p, d and f orbitals cannot occur until each orbital of a given subshell contains one electron each or is singly occupied.
