Transition metals are defined as those elements that have (or readily form) partially filled d orbitals. As shown in Figure 23.1.2 23.1. 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 ...

Big Idea: Properties of Matter - A. All objects and substances in the world are made of matter. Matter has two fundamental properties: matter takes up space and matter has mass which gives it inertia. B. Objects and substances can be classified by their physical and chemical properties. Mass is the amount of matter (or "stuff") in an object.

Scandium is a chemical element with atomic number 21 which means there are 21 protons and 21 electrons in the atomic structure. The chemical symbol for Scandium is Sc. Scandium is a silvery-white metallic d-block element, it has historically been sometimes classified as a rare-earth element, together with yttrium and the lanthanides.
transition metal, any of various chemical elements that have valence electrons—i.e., electrons that can participate in the formation of chemical bonds—in two shells instead of only one. While the term transition has no particular chemical significance, it is a convenient name by which to distinguish the similarity of the atomic structures and …
Example 1. Classify each of the following as either a physical property, or a chemical property: a) The boiling point of water is 100 o C b) Oxygen is a gas c) Sugar ferments to form alcohol Solution a) Although this property describes a change, this change does not involve a change in substance. H 2 O remains H 2 O despite what state it is in. . Thus, …
