Section 4. 1 Naming Binary Compounds

Section 4. 1 Naming Binary Compounds Objectives 1. To learn to name binary compounds containing only nonmetals (Greek Prefixes) 2. To learn to name Ionic compounds of a metal and nonmetal by balancing charges (Get a little gangsta!) 3. To learn to name Ionic compounds whose cation has more than 1 possible charge (Roman Numeral Notation)

Section 4. 1 Naming Binary Compounds A. Naming Compounds That Contain a Metal and a Nonmetal

Section 4. 1 Naming Binary Compounds A. Naming Compounds That Contain a Metal and a Nonmetal • For compounds containing both a metal and a nonmetal, the metal is always named first. The nonmetal is named from the root element name.

Section 4. 1 Naming Binary Compounds Why don’t we use the Greek Prefixes? • • Charge matters… Na charge? I charge? Only one balanced combination possible, so there is no need for the Greek prefixes… • Ca charge? • O charge? • Ca. O is the only balanced possibility…

Section 4. 1 Naming Binary Compounds Groups or Families • Table of common charges formed when creating ionic compounds. Oxide, Nitride Group or Family Charge Alkali Metals (1 A) 1+ Alkaline Earth Metals (2 A) 2+ Halogens (7 A) 1– Noble Gases (8 A) 0

Section 4. 1 Naming Binary Compounds Binary Ionic Compounds (Type I) Charge Matters! • Examples: Gangsta Switch! Potassium chloride Magnesium bromide Calcium iodide

Section 4. 1 Naming Binary Compounds • • • How about writing a formula from a name? CHARGE!! (10, 000 points each) Sodium Chloride Magnesium Sulfide Rubidium Bromide Calcium Oxide Barium Iodide Aluminum Fluoride Lithium Oxide Strontium Chloride Potassium Sulfide

Section 4. 1 Naming Binary Compounds A. What if the cation has more than 1 possible charge? Type II Binary Ionic compounds • Write the formula for Gold Chloride • Since the metal ion can have more than one charge, a Roman numeral is used to specify the charge. • Gold Chloride? Gold can have (+1) or (+3) charge • Au. Cl or Au. Cl 3? • Gold (I) Chloride or Gold (III) Chloride • Silver walks into a schoolyard….

Section 4. 1 Naming Binary Compounds A. Naming Compounds That Contain a Metal and a Nonmetal Type II Binary Ionic compounds (Iron II’s in a circle? ) Iron in the wind?
