Explain the trend and approximate magnitude of crystal field splitting for metal complex with the same type of
ligand when descending the group in the periodic table from 3d series to 4d and the charge inceases on the metal cation
Answers:
It has been many years since I even cracked the book on crystal field theory, but I refreshed myself a bit here:

Basically, the difference in splitting (delta value) decreases as you go down a group and increases by about 50% as you add positive charge on a metal cation. Other factors are covered on that page as well. Thanks for the reminder that I took a graduate inorganic chemistry class once back in the early 90's! I assure you that, at one time, I actually understood it, but I haven't used it in so long.well, you get the picture!
P.S. (I had forgotten that it replaced VB theory, which I was supposed to teach my students but ran out of time!)
do I look like I know that?
Don't you have a more difficult one?!? That one is just tooooo easy.
Don't be silly--you don't make sense 'cause you are not asking a real question.
