Write formulas for these compounds. dihydrogen . monosulfide.    . H. 2. I need to:. Write a formula. And I have:. 2 nonmetals. A metal and a nonmetal. A metal and a polyatomic ion. And I will:. Write the symbol for the element in the lowest group first. (exceptions – hydrogen always comes after carbon, and halogens always come before oxygen). Covalent Compounds. Formed between two non-metals. Valence electrons are shared between atoms. Binary Covalent Compounds. Contain just two different types of non-metal elements. Some Different Rules. Recognize that chemical formulas are used to identify substances and determine the number of atoms of each element in chemical formulas containing subscripts.. Recognize whether a chemical equation containing coefficients is balanced or not and how that relates to the law of conservation of mass.. Jennie L. Borders. Periodic Table for Naming. Section 9.1 Regular Metals Review. The . regular. metals include Group . 1. (except H) and . 2. and . aluminum. .. When . naming. a compound that starts with a regular metal, . Chapter 5: Molecules and Compounds. Learning Goals. Write . chemical formulas.. Determine . the total number of each type of atom in a chemical formula.. Classify . elements as atomic or molecular.. Classify . Naming Ionic Compounds. The names of ionic compounds consists of the names of the ions that make up the compound.. Names of . cations. include the elements of which they are composed.. Names of anions are altered names of elements.. I. onic compounds form between a metal and a nonmetal.. The metal forms a . cation. (+ ion) and the nonmetal forms an anion (-ion).. The . cation. is always named first and is the element name.. The anion is always named second – the root of the element name with an –ide ending.. General definitions. Mole. Homogeneous mixture.
