Give examples and suggest reasons for the l features of the transition metal chemistry: The lowest oxide of transition metal is basic, the highest is amphoteric/acidic.
Mn(II)O is basic and Mn2(VII)O7 is acidic. Cr(II)O is basic and Cr2(III)O3 is amphoteric. The ions in lower oxidation state can readily donate electrons and acts as bases and the ions in high oxidation states have a tendency to accept electrons and act as an acid.
