Presentation Transcript

  1. Ionic Compounds

  2. Determine the number of subatomic particles in the following elements: • Cl has a mass of 35 and an atomic # of 17 • p+ = 17, no = 18, e- = 17 • K has a mass of 39 and an atomic # of 19 • p+= 19, no= 20,e- = 19

  3. Write the formula of each of the following ionic compounds • Silver nitrate • Sodium oxalate • Magnesium hydroxide • Silver acetate

  4. Forming Ionic Compounds w/Variable Oxidation Numbers Some elements (metals) can have more than one possible charge when they form ions Use Roman Numerals to indicate their charge Example: Copper(II) Sulfate Chromium(III) Oxalate

  5. NotesNaming Ionic Compounds • Left  Right • Left Side: • Name the metal (cation) • If it is variable, you must use a roman numeral to indicate its oxidation number/charge • Right Side • If polyatomic and on your reference chart, write the name • If monatomic, write the name of the element but change the ending to “-ide”

  6. Practice • Write the name of each of the following compounds • AgBr • Ca3(PO4)2 • LiH • RaCl2

  7. NotesNaming Ionic Compounds w/Variable Oxidation Numbers • Start with what you know! (the anion) • Calculate the total anion charge • An ionic compound is neutral (no charge) so…. Total anion charge = Total cationcharge • Calculate the charge of the individual cation • Name the compound by giving the cation a roman numeral to represent its oxidation number (charge)

  8. Naming Ionic Compounds w/Variable Oxidation Numbers Example: Cu2S Ni(OH)2

  9. Name the compound BiI3 CoBr2

  10. Cu2S CuS

  11. Ionic Compounds Lab Review: signs of a chemical reaction

  12. Ionic Compounds Lab • Goggle safety • Dropper safety • Silver Nitrate – Sodium hydroxide safety • Equation set-up • Double Displacement Reactions • Clean Up

  13. Wrap Up What does the roman numeral tell you in an ionic compound? Assignment: Finish writing out all the reactions
