2017/4/23· Allotropic transformation When metals solidify, they assume a crystalline structure; that is, the atoms arrange themselves in a geometric lattice. Many metals exist in only one lattice form. Some, however, can exist in the solid state in two or more lattice forms, the particular form depending on the conditions of temperature and pressure.

19.1 Occurrence, Preparation, and Properties of …

Transition metals are defined as those elements that have (or readily form) partially filled d orbitals. As shown in Figure 1, 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 orbitals.
