  1. Ionic Compounds Review 1 12 / 2 / 09

  2. Admit Slip • What ions and ionic compound would Ca and F form?

  3. Objectives • Students will be able to: • Predict the ions that elements will form • Predict the ionic compound that two elements will form

  4. Agenda • Review Homework • Practice Problems • Homework

  5. Honors Homework p. 193 1. S-2 Al+3 2. a) Ba+2 2 lost b) As-3 3 gained c) Cu+2 2 lost 3. Valence electrons are equal to the column # 4. Nonmetal atoms gain e-. Metal atoms lose e-. 5. Cations + form when metal atoms lose e-. 6. Anions - form when nonmetal atoms gain e-.

  6. Honors Homework p. 193 7. Valence e- K: 1 C: 4 Mg: 2 O:6 9. Calcium: lose 2 Fluorine: gain 1 Aluminum: lose 3 Oxygen: gain 2 10. K  K+1 Zn  Zn+2 F  F-1

  7. Honors Homework p. 199 14. An ionic compound always has a 0 charge. 16. Ionic bonds form when anions - and cations + attract one another and form a compound. 18. K+1 S-2 K2S Ca+2 O-2 CaO Na+1 O-2 Na2O Al+3 N-3 AlN

  8. Honors Homework p. 199 19. Ba+2 Cl-1 BaCl2 Mg+2 O-2 MgO Li+1 O-2 Li2O Ca+2 F-1 CaF2 20. Cl and Br – No Li and Cl - Yes K and He – No I and Na - Yes
