Multiple Oxidation States Peak Mid-First-Series

The idea
Across the first transition series, oxidation-state count rises toward the middle and falls toward the ends, as later members retain more stable d electrons.
In practice
Manganese, near the middle, shows oxidation states from 2+ through 7+, more than scandium or copper at the ends.
Where people slip
"Transition metal" does not mean one fixed oxidation state — this variability is the group's defining signature.
