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 …
WebAns. (a) Valency: The number of hydrogen atoms which combine directly or indirectly with one atom of an element so as to form a compound is called valency. (b) When an atom donates electrons from a shell next to the valence shell, in addition to electrons of the valence shell, it exhibits variable valency.
