Presentation Transcript

  1. Honors Chem Ch 6 Pg 165Bonding • Ionic – transfers electrons, makes + and – ions that attract each other, strong solids, metal + non-metal, ex: NaCl • Covalent – shares electrons between non-metals, makes molecules, weaker liquids and gases, ex: H2O • Lewis Dot Notations – Pg 174

  2. Chapter 7Pg 209 Ionic Compounds • Writing Formulas – balance oxidation #s - D Block elements have Roman # for ox# • Naming compounds – “+” cation and “-“ anion, -ide - polyatomics Pg 214, –ate or –ite, not -ide Covalent Compounds pg 216-17 • Numeric prefixes for each element, last element ends in –ide • Don’t use prefix mono- for 1st element

  3. Formula Mass Pg 225 • Add masses of each element from pd table • Convert g to moles and moles to g Pg 228 given x wanted/given = wanted • Pg 230 Percent Composition = mass of elem/mass of compound x 100 • Pg 233 Empirical Formula = ratio of % • Pg 236 Molecular Formula – use ratio of molecular mass to empirical mass to multiply subscripts of empirical formula
