Part A:
Rank these transition metal ions in order of decreasing number
of unpaired electrons. If two ions have the same number of unpaired
electrons, overlap them such that the two appear in a single
column:
V3+, Mn4+, Ni2+, Fe3+, Cu+
Consider the following vanadium species. Arrange them in order
of strongest to weakest oxidizing agent:
[V(H2O)6]2+, [V(H2O)6]3+, [V(H2O)4O]2+, VO43−
