Formula writing and naming of metal-nonmetal binary compounds

Mastering Chemistry The chemicals that you will encounter during your chemistry course s will undoubtedly fall into many different categories: Each of these classes of compounds uses a unique naming system. In Chem I and II, you will be responsible for naming and writing formulas for commmon ionic compounds, binary molecular compounds, acids, and simple organic compounds. Since each of these classes of compounds uses a unique naming system, the first step in correctly naming a compound is to identify the type of compound that it is.

Formula writing and naming of metal-nonmetal binary compounds

Naming Polyatomic Ions At first glance, the nomenclature of the polyatomic negative ions in the table above seems hopeless. There are several general rules, however, that can bring some order out of this apparent chaos.

The name of the ion usually ends in either -ite or -ate. The -ite ending indicates a low oxidation state. Thus,the NO2- ion is the nitrite ion. The -ate ending indicates a high oxidation state. The NO3- ion, for example, is the nitrate ion. The prefix hypo- is used to indicate the very lowest oxidation state.

The ClO- ion, for example, is the hypochlorite ion. The prefix per- as in hyper- is used to indicate the very highest oxidation state. The ClO4- ion is therefore the perchlorate ion. There are only a handful of exceptions to these generalizations.

The names of the hydroxide OH-cyanide CN-and peroxide O ions, for example, have the -ide ending because they were once thought to be monatomic ions. Practice Problem 5 The bone and tooth enamel in your body contain ionic compounds such as calcium phosphate and hydroxyapatite.The rules for naming binary compounds are also illustrated by the following examples: As we said in the previous section, we can predict with certainty that each Group 1 metal will give a 1+ cation and each Group 2 metal will give a 2+ cation.

then it must be a polyatomic ion in the formula. Steps for naming Name the metal with its full name. When writing the. just like you did before with binary (only two elements) ionic compounds.

last worksheet When a polyatomic ion must be multiplied to make the compound neutral, parentheses must be used so that any subscripts added.

Naming Compounds Flowchart LOOK ON BACK FOR EXAMPLES OF EACH! Is there a METAL in the compound? YES NO Is the first element Hydrogen? Is the METAL a TRANSITION METAL? NO YES NO YES Acid Metal / Nonmetal Ionic Binary 3 or more elements Tran . GMT writing naming binary compounds pdf - Tutorials and Problem Sets.

Tutorials. Binary Compound (Metal/Nonmetal) with Fixed Charge Cation Given Formula, Write the Name; Given Name, Write the Formula Mon, 17 Sep GMT ChemTeam: Chemical Nomenclature - Chemical formula writing. Kids learn about naming chemical compounds in chemistry including conventions, order of the elements, metals, non-metals, (binary compounds).

The name of a compound with two elements has two words. Naming Metal-Nonmetal Compounds If one of the two compounds is a metal, then the naming convention changes a bit.
