Anions Cations Naming Ions Naming Ionic Compounds Writing Ionic Formulas Identify some Anions and Cations Anions Cations Metals Lose Electrons Cations Nonmetals tend to gain electrons Anions . 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. 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 . 6 Polyatomic Ions. Polyatomic Ions . Tightly bound groups of atoms that behave as a unit and carry a charge.. Ammonium . NH. 4. +. Cyanide. CN. -. Sulfite . SO. 3. 2-. Examples:. Common Polyatomic Ions. Chapter 4.10,4.11 and 5. Combining Elements. When we begin combining elements we make compounds.. Two types. Non-metal and metal. Non-metal and non-metal. Each type has unique physical and chemical properties. Dissolving Compounds. For . a substance to dissolve, . solute-solvent . attractions must overcome the . attractions . within both solute and solvent. . Example: In order to dissolve, ionic bonds must be broken by water. . 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.. 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.. Ionic bonds . result when electrons are transferred between atoms. Covalent bonds . result when valence electrons are shared between atoms. Types of Bonds. Formed between a . metal. and a . non-metal. 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.. Early in the 19. th. century John Dalton developed atomic theory. His theory explained the best available experimental data at that time. His theory has been modified since then with the discovery of other data, but his work was the initial ground work that we will examine first.. Students know . atoms combine to form molecules by sharing electrons to form covalent or metallic bonds or . by exchanging electrons to form ionic bonds. . . . Students know . salt crystals, such as . 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.
