Naming chemical compounds correctly is of paramount importance. Water The total charge of a compound is zero, the charge of the cation9s) should be balanced by the charge of anion(s) 3. Compound The chemical formulas of many molecules however, cannot be determined by using valencies. NAMING ORGANIC COMPOUNDS: 1 Important: These questions cover all the compounds on this page. When naming compounds, you need to understand these different rules, as well as how to spot clues that will help you properly name the compounds. in charge to the total oxidation number of the second, or negative, part of the compound. Naming basic chemical compounds is essential if you want to succeed in chemistry, since the name of the compound clearly defines what it is. CH 3-CH-CH=CH-CH3 CH3 This compound is named 4-methyl-2-pentene. why? Some of the worksheets below are Naming Compounds Worksheets : Covalent Compound Names and Formulas, Ionic & Covalent Compound Naming, Formulas and nomenclature of ionic and covalent compounds, Covalent Compounds Worksheet : Questions like Based of the properties of the following materials, determine whether they are made of primarily ionic compounds of covalent compounds… I have written the questions so that you can just answer those you … When you began chemistry class this year, you probably already knew that the chemical formula for car- bon dioxide was CO . Naming Ions. Naming ionic compounds: Name the cation then the anion. Another system of naming is needed. Naming compounds by mba06ht - Teaching Resources - Tes #143710. Naming and Writing Formulas for Acids! In this activity you will learn the naming system for molecu- lar compounds. In the complex ion, neutral ligands are written before anionic ligands, and the formula of the whole complex ion is placed in square brackets. Naming further compounds sheet 2. ppt, 71 KB.

The name of a monatomic cation is simply the name of the element followed by the word ion.Thus, Na + is the sodium ion, Al 3 + is the aluminum ion, Ca 2 + is the calcium ion, and so forth.. We have seen that some elements lose different numbers of electrons, producing ions of different charges (Figure 3.3). Naming Binary Compounds (compounds made of two different atoms): 1. Each of these three has its own rules that cannot be mixed and matched. A molecular compound is a group of atoms held together by a covalent bond. Each type of compound has its own rules for naming it. (Note: If the prefix of the first element would be “mono-”, it is not needed.)TIP! N2O3 dinitrogen trioxide 6. KF potassium fluoride 2. (If an element does not have a prefix, assume that the subscript is “1.” Third, apply the above naming scheme. If both atoms are in the same group, the … Naming coordination compounds involves a set of rules which includes the oxidation number of the central ion and the chemical composition of the ligand, focusing on the anionic and cationic properties of the molecule.
