However, the outermost s electrons are always the first to be removed in the process of forming transition metal cations. The absence of a layer of atoms in its densely packed structure, for example, enables a metal to deform plastically, and prevents it from being brittle. Transition Metal Ions. According to the Aufbau process, the electrons fill the 4 s sublevel before beginning to fill the 3 d sublevel. The elements are called "transition" metals because the English chemistry Charles Bury used the term in 1921 to describe the transition series of elements, which referred to the transition from an inner electron layer with a stable group of 8 electrons to one with 18 electrons or the transition from 18 electrons to 32.
