PPT-Section 1: Compounds and Chemical Formulas

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 . Ionic Compounds. Ionic Compounds. In this section…. Monatomic and Polyatomic ions. Ionic compound formulas. Naming ionic compounds. Covalent vs. Ionic compounds. Formation of Ions. Cations: Positive ions form by loss of electrons.. This topic will be investigated under five main headings:. Chemical Compounds. . Ionic Bonding. . Covalent Bonding. Electronegativity. . Shape of Molecules and Intermolecular forces. Chemical Compounds. CHEMICAL NOMENCLATURE. Writing Formulas. Binary ionic compounds. Ternary ionic compounds. Binary molecular compounds. Acids. Ionic Compounds. Composed of oppositely charged ions. Positive ion is a . cation. Write formulas for these compounds. dihydrogen . monosulfide.    . carbon disulfide. 29 mind challenges - You Ready?. Write formulas for these compounds. dihydrogen . monosulfide.    . H. 2. SECOND EDITION. Unit 1: ALCHEMY. Matter, Atomic Structure, and Bonding. Lesson 21: Salty Eights. Formulas for Ionic Compounds. ChemCatalyst. Find these cards in . Your Salty Eights . card deck.. 1. List the ionic compounds you can make with pairs of cards, using two different elements.. Simple Ionic Compounds. Concept:. Ionic Formulas are formed from positive and negative ions.. Fact 1:. Positive ions are formed by metals that lost electrons.. Examples: Na. 1+. Mg. 2+. A. 3+. 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.. Section 313 of SARA Title III. Why do I have to do TRI reporting?. A brief history of the Emergency Planning and Community Right to Know Act (EPCRA). Why was EPCRA legislated?. The Bhopal Site Today. Section 313 of SARA Title III. Why do I have to do TRI reporting?. A brief history of the Emergency Planning and Community Right to Know Act (EPCRA). Why was EPCRA legislated?. The Bhopal Site Today. 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. Heterogeneous mixture. Pure Substances. Compounds . Chemical Change . Chemical Property. Physical Change . Physical Property. Solid . Liquid . Gas. Evaporation. 3-. 2. Questions for Consideration. How do ionic compounds differ from molecular compounds?. What kinds of ions are in ionic compounds?. What do formulas for ionic compounds represent?. How are ionic compounds named?. Objectives. Compare chemical reactions to physical changes. Compare parts of an atom. Calculate the mass of one mole of an element or compound. Explain how ionic and covalent bonds are formed. Identify the parts of chemical equations.
