1.	Name the oxo metal anions in the first transition series in which the metal exhibits oxidation state equal to its group number.
Answer» From Sc to Mn the oxidation state leading to the maximum stability corresponding values of sum of 4s & 3d electrons. the element . Example: In group 3, Sc forms [Sc(III)O₂] ^-, in group 4, Ti forms [Ti(IV)O₃]^{2- ,}in group 5, V forms [V (V)O₃] ^-etc.
