An astrochemist analyzing a core sample from a newly discovered metallic asteroid isolates an element whose neutral atoms possess valence electrons in both an outer s orbital and an incompletely filled underlying d subshell. Laboratory tests show that this lustrous, high-density element readily forms emerald-green, azure-blue, and deep-purple solutions depending on its oxidation state. Based on its location in the Periodic Table and its physical and chemical properties, to which elemental family does this sample belong?
