Unit 5 Bonding and Nomenclature 5 1 Nomenclature

Unit 5: Bonding and Nomenclature 5. 1 Nomenclature • • Rules for nomenclature (naming) compounds Formula Writing A. Ionic B. Covalent C. Diatomic 5. 2 Bonding • Ionic and Covalent molecules D. Acids

Unit 5: Terminology List Nomenclature Acids Metals Bases Non-Metals Ionic Combining Capacity (C. C. ) Charges Covalent Bond Polyatomic Ions Roman numerals Diatomics prefixes

Part D. Acids Involves “H” hydrogen at the front of a chemical formula Recall our “Family of One” notes from Unit 3: Periodic Table and Trends Hydrogen acts likes a metal Becomes a H+ ion in solutions

I. Binary Acids Made up of two types of atoms HX H = metal X = non-metal For example: HCl becomes 1. hydrogen = hydro 2. Write “-ic” instead of “-ide” 3. acid goes on the end hydrochloric acid

LEARNING CHECK - Binary Acids 1. HI = 2. HBr = 3. hydrofluoric acid = 4. hydrosulphuric acid =

II. Ternary Acids Made up of MORE THAN two types of atoms H = metal HX#Y# X = non-metal Y = non-metal For example: HNO 2 becomes nitrous acid 1. drop hydrogen from the name 2. Write “-ic” instead of “-ate” 3. Write “-ous” instead of “-ite” 4. acid goes on the end I ate it, it was icy

LEARNING CHECK - Ternary Acids 1. HNO 2 = 2. HNO 3 = 3. sulphuric acid= 4. sulphurous acid =

II. Ternary Acids – Special Names There a lot of special names as well You don´t need to memorize them all! Examples: CH 3 COOH = H 2 CO 3 = H 2 C 2 O 4 =
