8.1: Chemistry of the Transition Metals - Chemistry LibreTexts

A transition metal is one that forms one or more stable ions which have incompletely filled d orbitals.On the basis of this definition, scandium and zinc do not count as transition metals - even though they are meers of the d block.. Scandium has the electronic structure [Ar] 3d 1 4s 2.When it forms ions, it always loses the 3 outer electrons and ends up with an argon structure.
