PPT-Section 3: Naming Ionic Compounds

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. Day 2. Working backwards: name to formula. It’s. . possible. . to. . determine. . a. . formula. . from. . a. . name. E.g. What is the formula of sodium oxide?. To get the answer, first write the valences:. 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.. Aqueous solutions of Sodium Hydroxide and Copper (II) Chloride combine to form an aqueous solution of . sodium. . chloride and . solid blue Copper Hydroxide . Write a skeleton equation. Balance the equation.. Putting electrical energy in to force the . nonspontaneous. change. electrolysis. Opposite process to electrochemical (voltaic) cells. Electrical energy is put into the reaction. The . nonspontaneous. 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.. 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.. Do Now: Identify ionic compounds. CO. 2. MgCl. 2. NH. 4. Cl. NaOH. NH. 3. CH. 4. CuSO. 4. HF. Magnesium’s outer shell is now empty. Fluorine’s outer shell is now full. Lewis Diagrams for Ionic Compounds. 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.. Net ionic equations are useful in that they show only those chemical species directly . participating in . a chemical . reaction. The keys to being . able to . write net ionic equations are the ability to recognize monatomic and polyatomic ions, . 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?.
