Vedclass · Answer

(D) The elements provided include lanthanoids ($Eu$,$La$,$Gd$) and an actinoid $(Am)$.Actinoids exhibit a greater range of oxidation states compared to lanthanoids due to the comparable energies of $5f$,$6d$,and $7s$ orbitals.$Am$ (Americium) exhibits oxidation states ranging from $+2$ to $+6$ (and sometimes $+7$ in specific conditions).In contrast,lanthanoids like $La$,$Eu$,and $Gd$ primarily show the $+3$ oxidation state,with $Eu$ also showing $+2$ and $Gd$ showing $+3$ as its most stable state.Therefore,$Am$ shows the maximum number of different oxidation states.

Which of the following elements shows the maximum number of different oxidation states in its compounds?
