WebFeb 17, 2024 · Some of the transition elements show variable valency because of the different electronic configuration. Sometimes an atom of an element loses its electron from the penultimate shell and thus has more than $1$ valency. For example, Iron forms ferric and ferrous oxide. Iron has $ + 2$ oxidation state at ferrous oxide whereas iron shows $ … WebSome elements show variable valency because of the different electronic configurations. An atom of an element can sometimes lose more electrons than are present in its valence shell i.e. loss from the penultimate shell because its electrons are in a highly excited state. These are the elements that exhibit more than 1 or variable valency. 25 marshall avenue st leonards nsw 2065 WebMar 19, 2024 · Some elements show variable valency because of the different electronic configurations.

Transition metals have variable valencies because the energies of the 3d orbital and 4s orbitals (or similar orbital comparisons in lanthanides and actinides, etc.) are similar, so electrons are able to bond from the d-shell as well. Kind of similar to how some high atomic number elements are able to violate the octet rule, such … box iphone ibox
