WebNov 26, 2024 · It is well known that noble gases have closed electronic shell structure and hence have high ionization potentials and low electron affinities, due to which they are chemically inert and resistant to salt formation under most conditions. Affinities of Nonmetals vs. Affinities of Metals WebThe stable oxidation states of cerium are Ce 3+ and Ce 4+, presenting in the two respective oxides named cerium dioxide or ceria (CeO 2) and cerium sesquioxide (Ce 2 O 3). The 4+ oxidation state of cerium is considered more stable due to the fact that its electronic structure is identical to a noble-gas configuration (i.e., [Xe] 4f 0 ) compared ...
