Download Solution PDFThe correct answer is Option 2, i.e Transition Elements.
Important Points
- There are elements which differ in the capacity to combine with other elements.
- This depends on the nature of the reaction.
- The property of such kind of elements is called variable valency.
- For example, the iron in ferrous oxide exhibits a valency of +2, whereas in ferric oxide, it has a valency of +3.
- The transition elements are those elements having a partially filled d or f subshell in any common oxidation state.
- The term "transition elements" most commonly refers to the d-block transition elements.
- Variable valency is thus exhibited by the Transition elements due to partially filled subshells.
