[general chemistry] is the electron configuration of the metal cation or something else the reason [Cr(H2O)6]3+ is d2sp3 but [Co(H2O)6]3+ is sp3d2?

Why is "In half-filled subshell configurations, there is a maximum in the effective nuclear charge felt by the electrons (compared to the previous elements with no doubly-occupied orbitals)" not off-topic response to a question on the trends in melting/boili' point in first series transition elemen?
