What would the term symbol be of a transition metal ion with d2 configuration in which maximum multiplicity was found?
Accepted Answer
The term symbol for a transition metal ion with a d² configuration and maximum multiplicity would be ³F. Here's why:
d² Configuration: This means the ion has two electrons in its d orbitals.
Maximum Multiplicity: To maximize multiplicity, we need to align the spins of the electrons in the same direction. This is achieved by placing one electron in each of the five d orbitals with spin up (ms = +1/2).
Term Symbol: The term symbol is derived from the total orbital angular momentum (L) and the total spin angular momentum (S).
L: For a d² configuration, with two electrons in separate d orbitals, L = 2 (since the d orbitals have l = 2). The corresponding spectroscopic term is F.
S: With both spins aligned, S = 1. The multiplicity is 2S+1 = 3 (triplet).
Therefore, the term symbol is ³F.
