3. This morning I slipped in some mystery liquid in the kitchen with the toaster, luckily for me I was not electrocuted, based on this do you think I was in an ionic or molecular compound?

5. How do we name and represent different substances? Day 5 3-1

6. Chemical bonds that result from the electrical attraction between large numbers of cations and anions Cation – ? Anion – ? Ionic bonds – REVIEW

7. Ionic bonds most commonly form between …? REVIEW Ionic bonds are made up of charged pieces (ions) … Ions can be made up of single atoms or groups of atoms bonded together (polyatomic ions)

8. Anion Electrostatic force Electronegativity Nonpolar covalent bond Stable Penn State Chemical bond Cation Octet rule Valence electrons

9. 1.Get out the new notes. What is a binary ionic compound? Day 1 3-5

10. Binary ionic compound – ionic compound consisting of only 2 elements (monatomic ions) Naming: Name the cation and add an ide ending to the anion

11. Examples: sodium and chlorine form… sodium chloride magnesium and oxygen form… magnesium oxide

12. Bromine bonds with sodium Cesium bonds with oxygen Silver bonds with fluorine Sodium bromide Cesium oxide Silver fluoride

13. chlorine bonds with lithium magnesium bonds with sulfur aluminum bonds with oxygen Lithium bromide Magnesium sulfide Aluminum oxide
