The manganese(ii) ion is known to have d5 configuration having the following term symbols: 4g, 4d, 4f, 6s, 4p. the term symbol of highest energy would be?
Accepted Answer
The term symbol with the highest energy is 6S. Here's why:
Hund's Rules: Hund's rules dictate the order of energy levels in atomic orbitals. The rule that applies here is that the term symbol with the highest spin multiplicity (highest value of S) will have the highest energy.
Spin Multiplicity: The spin multiplicity (2S+1) for 6S is 7 (S=3), while all other term symbols have lower spin multiplicities.
Therefore, the 6S term symbol, with its higher spin multiplicity, represents the highest energy state.
