1.3 Physical and Chemical Properties – Chemistry
Physical properties, such as hardness and boiling point, and physical changes, such as melting or freezing, do not involve a change in the composition of matter. Chemical properties, such flammability and acidity, and chemical changes, such as rusting, involve production of matter that differs from that present beforehand.

Properties of Minerals | Earth Science | Visionlearning
Identifying minerals by physical properties The most common minerals in Earth''s crust can often be identified in the field using basic physical properties such as color, shape, and hardness. The context of a mineral is important, too – some minerals can form under the same conditions, so you are likely to find them in the same rock, while others form under very different conditions and will

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 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.
