Valence-shell Configuration for Transition Metals

Postby Angel Ni 2K » Mon Oct 30, 2017 9:06 pm

For HW problem 2.55 c, we are asked to write the valence-shell configuration for the Group 5 transition metals. I got (n-1)d3 ns2, but the answer key says (n-1)d5 ns2. Does the question mean to ask for the fifth group of transition metals or is there some special property of Group 5 metals that makes them have an unpredictable valence-shell configuration?

I believe by "group 5 transition metals" it means the fifth column of the transition metals starting with Mn, and not group 5 of the periodic table. If you use the fifth column then it gives you (n-1)d^5ns^2 like in the solutions manual.
