WebApr 6, 2024 · Variable valency is shown by elements like Iron, mercury, and copper. Transition elements show variable valency. For example: in some cases, iron shows a … WebMar 17, 2024 · Since, both zinc and mercury have completely filled d-orbital. So, they tend to lose only 2 electrons from their outermost shell. Hence, only show a valency of +2 and no variable valency. Thus, we can conclude that zinc and mercury do not show variable valency like d-block elements because their d-shells are complete.
WebValency of Iron: The atomic number of iron is 26. The electronic configuration of the element is: 1 s 2 2 s 2 2 p 6 3 s 2 3 p 6 4 s 2 3 d 6. Therefore, the valency of iron is 2 and 3.
