Classification scheme for matter

The entire classification scheme for matter discussed in this section is outlined in Table 1.1 and Figure 1.1. 

A Figure 1.9 Classification scheme for matter. At the chemical level all matter is classified ultimately as either elements or compounds. 

FIGURE 1 -4 Classification scheme for matter. Matter may be either a pure substance or a mixture. If it is a pure substance, it may be either an element or t compound. If it is a mixture, it may be either a homogeneous mixture or a heterogeneous mixture. 

Classification of Matter This classification scheme for matter shows the relationships among mixtures, compounds, and elements.

Quarks carry a fractional charge of Vj or Fy Six flavors or types of quarks make up all subatomic particles. Each flavor of quark can be fiufher classified as having one of three colors. These are not colors or flavors as commonly thought of, but part of a classification scheme used to explain how matter behaves. The language of quarks makes them seem like some creation of fantasy, but the quark theory can be used to explain many properties of subatomic particles. For example, a proton can be considered to be made of two up quarks and a down quark, and a neutron of two down quarks and an up quark (Figure 4.8). Quark flavors and charges are given in Table 4.5.

Since the nomenclature problem is a matter of communication, a glossary is necessary. This leads naturally to the scheme for systematizing zeolites by structural classification. 

In the second edition" of his textbook, he dedicated a particular chapter to the periodic system (eight pages out of 475). He emphasized that the classification scheme presented was not yet in its final form. Nevertheless, the introduction of the periodic system—an important tool for combining numerous information, which before had no established relationships to one another—in chemical textbooks was no longer pushed aside. Richter believed it was possible to reason from the periodic dependence of the properties of atomic weight that the different elemental atoms are aggregates or a condensation of one and the same primary matter, but not hydrogen.
