Metals binary ionic compound

In general, binary compounds of two nonmetals are molecular, whereas binary compounds formed by a metal and a nonmetal are ionic. Water (H20) is an example of a binary molecular compound, and sodium chloride (NaCl) is an example of a binary ionic compound. As we shall see, these two types of compounds have... 

Stable binary ionic compounds are formed from ions that have noble gas configurations. None of the compounds meet this requirement. First of all, C04 is not an ionic compound at all because it is a covalent compound, made from 2 nonmetals. Even so, C04 is not stable because with O2, C would have an oxidation number of +8, which is very unlikely. Consider the following ionic compounds composed of a metal and... 

An ionic compound is one that is composed of (positively charged) cations and (negatively charged) anions. Most binary ionic compounds are composed of a metal (which becomes the cation) and a nonmetal (which becomes the anion). 

Ionic compounds consist of positive ions (cations) and negative ions (anions) hence, ionic compounds often consist of a metal and nonmetal. The electrostatic attraction between a cation and anion results in an ionic bond that results in compound formation. Binary ionic compounds form from two elements. Sodium chloride (NaCl) and sodium fluoride (NaF) are examples of binary ionic compounds. Three elements can form ternary ionic compounds. Ternary compounds result when polyatomic ions such as carbonate (C032 ), hydroxide (OH-), ammonium (NH4+), form compounds. For example, a calcium ion, Ca2+, combines with the carbonate ion to form the ternary ionic compound calcium carbonate, CaC03. Molecular compounds form discrete molecular units and often consist of a combination of two nonmetals. Compounds such as water (H20), carbon dioxide (C02), and nitric oxide (NO) represent simple binary molecular compounds. Ternary molecular compounds contain three elements. Glucose ( 12 ) is a ternary molecular compound. There are several distinct differences between ionic and molecular compounds, as summarized in Table 1.2. 

Assume that 1.588 g of an alkali metal undergoes complete reaction with the amount of gaseous halogen contained in a 0.500 L flask at 298 K and 755 mm Hg pressure. In the reaction, 22.83 kj is released (AH = —22.83 kj). The product, a binary ionic compound, crystallizes in a unit cell with anions in a face-centered cubic arrangement and with cations centered along each edge between anions. In addition, there is a cation in the center of the cube. 

Structure of Simple Binary Ionic Compounds.—To be electrically neutral, every ionic compound must contain some positive and some negative ions. The simplest ones are those binary compounds that contain one positive and one negative ion. Obviously the positive ion must have lost the same number of electrons that the negative one has gained. Thus monovalent metals form such compounds with monovalent bases, divalent with divalent, and so on. In other words, this group includes compounds of Li+, Na+, K+, Rb+, Cs+, Cu+, Ag+, and Au+ with F-, C1-, Br, I- of Be++, Mg++, Ca++, Sr++, Ba++, Zn++, Cd++, Hg++, with 0—, S—, Se—, Te of B+++, A1+++, Ga+++, In+++, T1+++, with... 

Binary ionic compounds are compounds composed of two monatomic ions. These usually are a metallic cation and a nonmetallic anion. When naming these compounds, there are a few rules that need to be followed ... 

A binary compound is an inorganic compound that contains two elements. Binary compounds may contain a metal and a non-metal or two non-metals. Binary compounds are often ionic compounds. To name a binary ionic compound, name the cation first and the anion second. For example, the compound that contains sodium and chlorine is called sodium chloride. 

Binary Ionic Compounds Binary ionic compounds are ionic compounds that have just two different elements present. Examples are NaCl and Mgl2. When naming a binary ionic compound, name the metal first and then name the non-metal with the ending -ide. There are no prefixes used when naming binary ionic compounds. The names of the example above are sodium chloride and magnesium iodide. 

Type II binary ionic compounds with the metal possessing more than one type of cation... 

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 ... 

When a nonmetal and a representative group metal react to form a binary ionic compound, the ions form so that the valence electron configuration of the nonmetal is completed and the valence orbitals of the metal are emptied. In this way both ions achieve noble gas electron configurations. 

All the binary ionic compounds formed by an alkali metal and a halogen have the structure shown in Fig. 13.9, except for the cesium salts. The arrange-... 

We have already seen that when metals and nonmetals react to form solid binary ionic compounds, electrons are transferred and the resulting ions typically have noble gas electron configurations. An example is the formation of KBr, where the K ion has the [Ar] electron configuration and the Br- ion has the [Kr] electron configuration. In writing Lewis structures, the rule is that... 

Name the following binary ionic compounds. If the metal forms more than one cation, be sure to denote the charge. 

Hundreds of compounds contain ionic bonds. Many ionic compounds are binary, which means that they contain only two different elements. Binary ionic compounds contain a metallic cation and a nonmetallic anion. Magnesium oxide, MgO, is a binary compound because it contains the two different elements magnesium and oxygen. However, CaS04 is not a binary compound. Can you explain why ... 

Most metals react with most nonmetals to form binary ionic compounds. The Group lA metals combine with the Group VIIA nonmetals to form binary ionic compounds with the general formula MX (Section 7-2) ... 

Binary ionic compounds contain metal cations and nonmetal anions. The cation is named first and the anion second. 

The preceding method is sufficient for naming binary ionic compounds containing metals that exhibit only one oxidation number other than zero (Section 4-4). Most transition metals and the metals of Groups IIIA (except Al), IVA, and VA, exhibit more than one oxidation number. These metals may form two or more binary compounds with the same nonmetal. Ta distinguish among all the possibilities, the oxidation number of the metal is indicated by a Roman numeral in parentheses following its name. This method can be applied to any binary compound of a metal and a nonmetal. 

The free halogens react with most other elements and many compounds. For example, all the Group lA metals react with all the halogens to form simple binary ionic compounds (Section 7-2). 

To name a binary ionic compound, first write the name of the positively charged ion, usually a metal, and then add the name of the nonmetal or negatively charged ion, whose name has been modified to end in -ide. The compound formed from potassium and chlorine is called potassium chloride. Magnesium combines with oxygen to form a compound called magnesium oxide. 

Binary ionic compounds are named by first naming the metal element and then the non-metal element, with its ending changed to -ide. Subscripts are used in formulas to indicate how many atoms of each element are present in the compound. 

Before you can write a chemical formula from the name of a compound, you need to recognize what type of compound the name represents. For binary ionic compounds, the first part of the name is the name of a metallic cation. This may include a Roman numeral in parentheses. The anion name starts with the root of the name of a nonmetal and ends with -ide. 

Binary ionic compound An ionic compound whose formula contains one symbol for a metal and one symbol for a nonmetal. 

As we saw in Chapter 3, this transfer of electrons from metal atoms to nonmetal atoms is the general process for the formation of any binary ionic compound from its elements. For example, when sodium chloride is formed from the reaction of metallic sodium with gaseous chlorine, each sodium atom loses an electron, and each chlorine atom gains one. 

A binary Ionic compound is one composed of ions from only two elements, one a metal, the other a nonmetal. NaCl, CaF2, and FeCl3 are all binary ionic compounds. Before starting to develop formulas for ionic compounds, it is necessary to know the monatomic ions (ions formed from a single atom) of the common metals and nonmetals. 

Naming binary ionic compounds in which the metal forms only a single cation is not difficult. 

The rules for naming binary ionic compounds with single-cation metals are as follows ... 

Ionic compounds that contain polyatomic ions are named in the same way used to name binary ionic compounds. Attention must be paid as to whether the cation is a metal that forms a single cation or multiple cations, and the name of the polyatomic ion is that given in the table. Note how these six ionic compounds are named ... 

The first member of Group 3A, boron, is a metalloid the rest are metals (Figure 8.16). Boron does not form binary ionic compounds and is unreactive toward oxygen gas and water. The next element, aluminum, readily forms aluminum oxide when exposed to air ...
