1. Chem A Review Covalent or Ionic, that is the ?

2. Ionic Compounds

3. We all want to be rockstars! Atoms want to be Noble gases Why??? FULL OUTER SHELL

4. ION Formation P = 11 e = 11 Charge = 0 P = 11 e = 10 Charge = +1

5. CATION Positively charged atom

6. ANION Negatively charged atom

7. Ionic Compounds Na O +1+1 -1 + 1 -2

8. Oxyanions POLYATOMIC ANIONS WITH O and another non-metal SO 4 2- CO 3 2-

9. Oxyanions Most OPer-ate -1 O -ate -2 O -ite -3 Ohypo-ite +1 Oper - ate O n - ate -1 O - ite -2 Ohypo - ite Top Down Most Common

10. Polyatomics to KNOW Ammonium Hydroxide Sulfate Phosphate Nitrate Carbonate NH 4 + OH - SO 4 2- PO 4 3- NO 3 - CO 3 2-

11. Oxyanions NaClO 4 sodium perchlorate Al 2 (SO 4 ) 3 aluminum sulfate CaCO 2 calcium carbonite K 3 PO 2 potassium hypophosphite

12. Covalent Molecules

13. Binary Covalent Rules 1) Left to Right 2) “-ide” be back! 3) Junkies need their PRE-fix a.EXCLUDE MONO on first element

14. Pre---FIXES Mono Di Tri Tetra Penta Hexa Hepta Octa Nona Deca 1 2 3 4 5 6 7 8 9 10

15. Practice CCl 4 As 2 O 3 Br 2 H 2 O 2 NF 3 Carbon tetrachloride Diarsenic trioxide Bromine Dihydrogen dioxide Nitrogen Trifluoride
