The procedure followed in naming the chemical compounds was the identification of the compound that contains metal and a non-metal (Speight and James 47). After the identification then it was later grouped into classes and various groups according to the periodic table. The results were a table consisting of both molecular and non-molecular compounds. The names of various chemical compounds were also written. Objectives To understand the rules of naming organic and molecular compounds. In naming the compound the cation and the anion name are thus added together to form a compound. If the cations have taken many charges, the charge is thus denoted using Roman numerical in parenthesis immediately following the element name. There are cases where some metallic ions form the cations and therefore contain different positive charges; the names must contain some of the indications of cation charge.

Molecular compounds also are named in a special way with a systematic approach of prefixes to denote the number of the element that is present in the compound. The IUPAC system of naming is used in this case Rules for Naming Molecular Compounds a) The ending is removed the second element, and “ide” is added similar to ionic compounds b) In naming molecular compounds prefixes are used to dictate the number of a given element present in the compound. Then add -ide to the root of the second element. c. If the compound is ionic, determine if the metal ion (cation) has a fixed or variable charge. Record the name of the cation followed by the root name of the anion with the suffix “-ide” if the anion is only one type of element or the full name of the polyatomic ion.

For cations with a variable charge, be sure to include the correct Roman numeral to record the name of a neutral compound by ensuring the sum of the charges for the anion and the cation equal 0. Be sure to include the correct number of atoms to record the formula of a neutral compound by ensuring the sum of the charges for the anion and the cation equal 0. Results Data Table 5.
