Na Al 3 S 2 2Ca 2 PO 4 3 3Cl Review forming ions Ionic ie salt refers to ve ion plus ve ion Usually this is a metal nonmetal or metal polyatomic ion eg NaCl NaClO. 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 = -). Ionic w/Transition. Metals. Ionic w/ Polyatomic. Covalent. Writing. Formula from Name. Write out ions, . criss. cross number. of charge to make subscripts, reduce. Write out ions, . criss. cross number. Paul F. Aubin. Paul F. Aubin. Create a Parametric Ionic Column from Start to Finish. Will update this page when venue is determined. Objectives. Constructing the Ionic . volute. Creating the Ionic capital using the volute profile. 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. Very Important!. Going down the periodic table the properties are affected by INCREASING SIZE and INCREASING DISTANCE between the nuclei and the valence . e-s. Going across a period, properties are affected by the DIFFERING VALENCE, NUCLEAR CHARGE and CHARGE ON THE SPECIES. SCH4U1. Mr. . Dvorsky. Ionic Solids. Result from the reaction of a metal and a non-metal. Because of the large . electronegativity. difference, electrons transfer from the metallic atom to the non-metallic atom and the ions that result attract each other. . 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. Electrons are transferred from an atom of low electronegativity to one of high electronegativity. Anion (-) and cation ( ) formed. Opposite charges attract – called an . electrostatic force. Formula Unit. Chapter 7. An . ion. is an atom that has gained or lost electrons from the valence shell.. Valence electrons. are the electrons contained in the highest occupied energy level. These electrons will mostly determine the chemical properties of the element. Focus on equations with a precipitate.. Total Ionic Equations. Write the equation . (synthesis, decomposition, etc. .). check . for reactants and products that are . soluble. or . insoluble. .. We usually assume the reaction is in . 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.. 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 . Chemical Interactions Occur between the Valence Electrons. Dots. : represent . valence electrons. When atoms combine to make molecules, they form . chemical bonds.. Valence . electron . interaction.
