19.1 Occurrence, Preparation, and Properties of Transition

Transition metals are defined as those elements that have (or readily form) partially filled d orbitals. As shown in Figure 19.2, the d-block elements in groups 3–11 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f …
