Part 10. 3d block – Transition Metals – 10.3 Scandium Chemistry Scandium is a member of the 3d–block of elements BUT why isn't scandium a true transition metal? Scandium cannot form an ion with an incomplete 3d sub–shell and is therefore not a true transition element. Scandium's chemistry is determined solely by the formation of compounds in its +3 oxidation state, but it does form many complexes, though not as many as other transition metals. principal oxidation states of scandium, redox reactions of scandium, ligand substitution displacement reactions of scandium, balanced equations of scandium chemistry, formula of scandium complex ions, shapes colours of scandium complexes, formula of compounds
