Question

A particular transition metal has the possible ground state term symbols of singlet S, singlet D, singlet G, triplet P, and triplet F. In each case, determine the allowed values of J. If the d shell i C. less than half full, what is the ground state term symbol according to Hund's rules? The ground state term symbol for Nb (element 41) is GD 1/2 . What electron configuration is D.

Question C

Answer 1

Tomic Term symbol 2011 where, s-Total spin quantenas. I slotal orbitall quanton no. I = Total angular momentin quantem no.

Again for Ground hat L=3 first the multiplicity rule is applied, which states that the same having highest spin multiplicity is ground state trong

G. 'D'S 3 Sp both Br and sp saksfy these Thill. So, we have to apply the second rule of higher value Larger the value tower bill be the energy. So, between of and Sp.
