Created with Fabric.js 1.4.5 MOLECULAR COMPOUNDS COOL FACTS IONIC COMPOUNDS VS COOL FACTS NAMING FORMULA WRITING PROPERTIES 1. Many are soluble in water but not in a non polar liquid2. All ionic compounds form crystals3. Are very hard and brittle NAMING FORMULA WRITING PROPERTIES The bonding between a non-metal and a metal, that occurs when charged ions attract after one looses one or more of its electrons, and gives it to the other molecule. 1. Identify the cation(metal)2. Identify the anion(non-metal)3. Add -ide ending to the non-metal4. If polyatomic the -ide ending is not needed 1. Write the symbols for cation and anion2. Determine the charge of cation and anion3. If the cation is a transition metal include Roman numerals to indicate charge DEFINITION A chemical bond that involves the sharing of electron pairs between two non-metals. 1. Use prefixes to indicate the subscript of each element in the formula2. Write correct symbols for two elements with appropriate subscripts Ionic and molecular (covalent) bonds are two different ways of chemical bonding. DEFINITION 1. Low melting and boiling points2. Poor electrical conductors in all phases3. Solid, liquid, or gas at room temperature 4. Have no charges 1. Identify the two non-metal names2. Add -ide ending to the last non-metal3. Add prefixes to indicate the number of the given element present 1. High melting and boiling points2. Conduct electricity when melted3. Solid at room temperature4. Have positive and negative charges EXAMPLES 1. NaCl = Sodium Chloride2. KBr = Potassium Bromide3. CaCl2 = Calcium Chloride EXAMPLES 1. H2O = Hydrogen dioxide2. NF3 = Nitrogen trifluride3. S2F10 = Disulfur decafluroide Madeline Moody
