Chemistry – Jan 12, 2018 P3 Challenge- Agenda ACT Friday Objective – Ionic compound formation Assignment: Start Ionic Compounds Worksheet Agenda ACT Friday IMF Homework review Writing ionic formulas

Writing Ionic Formulas – SHORT CUT Because compounds are electrically neutral, one can determine the formula of a compound this way: The charge on the cation becomes the subscript on the anion. The charge on the anion becomes the subscript on the cation. If these subscripts are not in the lowest whole-number ratio, divide them by the greatest common factor. “Switch, Drop and Reduce”

Writing Ionic Formulas Practice Predict ionic compounds that form using the exponent switch drop and reduce process to create a neutral formula. Formula always written with cation (metal) first Ex: compound formed by barium and chlorine Ex: compound formed by aluminum and oxygen

Writing Ionic Formulas Practice (cont) Ex: compound formed by sulfur and sodium Ex: compound formed by Fe+2 and oxygen Ex: compound formed by barium and hydroxide Use parentheses anytime you need more than one of a polyatomic ion

Three types of ionic compounds Type 1 - Binary compound (contains only two elements) and cation charge is known because atom can form only one type of ion. Metal forms only one type of ion: Groups 1A, 2A, Al3+, Ga3+, Zn2+, Cd2+, and Ag+ Type 2 – Binary compound with variable charge cations. Transition metals and representative metals. Type 3 – Polyatomic ion compound contains three or more elements contained within one or two polyatomic ions.
