Type I binary compounds

Formulas from Names for Type I Binary Compounds... 

Type I binary compound containing the Li and (peroxide) ions. 

In this section we will consider binary ionic compounds of two types based on the cations they contain. Certain metal atoms form only one cation. For example, the Na atom always forms Na", never Na or Na ". Likewise, Cs always forms Cs, Ca always forms Ca, and A1 always forms Al. We will call compounds that contain this type of metal atom Type I binary compounds and the cations they contain Type 1 cations. Examples of Type 1 cations are Na, Ca, Cs, and AL. ... 

Type III binary compounds are neutral, covalent compounds that contain two nonmetals. Type III naming is similar to Type I and II using the following rules ... 

A Type I binary ionic compound contains a metal that forms only one type of cation. The rules for naming Type I compounds are illustrated by the following examples ... 

We will call compounds fhaf confain fhis fype of metal atom Type 1 binary compounds and the cations they contain Type I cations. Examples of Type 1 cations are Na", Ca ", Cs", and Al +. 

OBJECTIVE To review the naming of Type I, Type II, and Type III binary compounds. 

In this chapter, I shall discuss the limiting types of binary compound. I shall do this on the assumption that matter is composed of atoms, but without any reference to the structure of the atom as we now understand it. This something that I shall bring in later. 

Solid solutions are very common among structurally related compounds. Just as metallic elements of similar structure and atomic properties form alloys, certain chemical compounds can be combined to produce derivative solid solutions, which may permit realization of properties not found in either of the precursors. The combinations of binary compounds with common anion or common cation element, such as the isovalent alloys of IV-VI, III-V, II-VI, or I-VII members, are of considerable scientific and technological interest as their solid-state properties (e.g., electric and optical such as type of conductivity, current carrier density, band gap) modulate regularly over a wide range through variations in composition. A general descriptive scheme for such alloys is as follows [41]. 

The distribution of componentsof binary solid solutions over the solid phase and the aqueous phase has been studied for a number of systems. Table I contains a summary of some of these systems with references. This literature review is not complete more data are available especially for rare earth and actinide compounds, which primarily obey type I Equations to a good approximation. In the following sections, the theory above will be applied to some special systems which are relevant to the fields of analytical chemistry, inorganic chemistry, mineralogy, oceanography and biominerals. 

Problem Formulation. The conditions of equilibrium require the equivalence in each phase of temperature, pressure, and chemical potential for each component that is transferable between the phases and are subject to constraints of stoichiometry. A statement of the equivalence of chemical potential is identical to equations 8 and 9. An example is the AJB C D quaternary system. This system contains four binary compounds, AC, BC, AD, and BD, and the conditions of equilibrium allow three equations (of the type given by equation 8) to be written. The fourth possible equation is redundant as a result of the stoichiometric constraint (i.e., equal number of atoms on each sublattice).
