PPT-Ionic Compounds and Naming

Chapter 410411 and 5 Combining Elements When we begin combining elements we make compounds Two types Nonmetal and metal Nonmetal and nonmetal Each type has unique physical and chemical properties. 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.. IUPAC. BOHR DIAGRAMS FOR ATOMS. TYPES OF CHEMICAL BONDS. MOLECULAR COMPOUNDS. TYPES. SIMPLE COVALENT. COMMON NAME. IONIC COMPOUNDS. SIMPLE IONIC. MULTIVALENT. POLYATOMIC/COMPLEX. HYDRATED IONIC. ACIDS. Ch. . 16. Covalent Compounds. Covalent bonds. form when atoms share . their valence electrons. .. Covalent compounds. are formed from 2 or more nonmetals.. Rules for Naming Covalent Compounds. 1. Prefixes are used to show how many atoms of each element are present in the compound . Fancy word for naming and formulas. Rules. You did a lot of naming in grade 9, we will expand now. All elements have symbols. Metals on the left side. Non-metal on the right side. Separation is the stair-case. Including Naming. Note: We likely won’t make it to covalent nomenclature, this is the one students find FAR easier than ionic. Please refer to the videos and naming hand out for help with this, and as always office hours, discussions, and . Ionic Bonding and Writing Formulas. Common Anion Name Changes. Nitr. ogen .  . Phosph. orus .  . Ox. ygen .  . Sulf. ur .  . Selen. ium .  . Fluor. ine .  . Chlor. ine .  . Brom. Copyright © by Holt, Rinehart and Winston. All rights reserved.. Objectives. Name . simple ionic . compounds. .. Predict . the charge of a transition metal . cation. in an ionic compound.. Write . chemical formulas for simple ionic compounds.. MACROSCOPIC SCALE. Elements combine to make compounds.. ATOMIC SCALE. Atoms combine to make molecules, or extended structures.. What we’ll cover…. Compound Formulas. Ions. Monatomic. Polyatomic. Ionic Compounds. Steps:. 1.) . Cation. is written before anion.. 2.) Charges must cancel. (ionic compounds are neutral). 3.) Atoms must be in smallest whole number ratio.. Write the formula units for the following ionic compounds: 1.) lithium chloride, 2.) strontium oxide, 3.) ammonium phosphate.. Oxyanions. Oxyanions- negative ions containing oxygen.. These have the suffix “-ate” or “-ite”. “-ate” means it has more oxygen atoms bonded, “-ite” has less. For example. SO. 4. 2-. sulfate. 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.. Chapter 5: Molecules and Compounds. Learning Goals. Distinguish . between common and systematic names for compounds. . Name . binary ionic compounds containing a metal that forms only one type of ion.. 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?. Chemical Interactions Occur between the Valence Electrons. Dots. : represent . valence electrons. When atoms combine to make molecules, they form . chemical bonds.. Valence . electron . interaction.
