4. Review Exit Slip

5. Lewis Dot Practice Li Si Ar O Mg Cl N B

6. Oxidation numbers and Ionic Bonding
PS-4.3 Illustrate the fact that ions attract ions of opposite charge from all directions and form crystal lattices.

7. Ionic Bonding Bond between metals and nonmetals
Provide chemical stability by losing and gaining electrons.
Elements form ions.
Ions: a charged particle.
Oxidation state: Number of electrons, lost, gained, or shared to form compounds

8. Before we get started you need to know what an ion is

9. Cation = positive ion
Anion = negative ion

10. Ionic Bonds
1. Metals
Lose electrons
Form positive ions

11. Ionic Bonds A. Group 1 Alkali Metals Lose or transfer 1 electron
1+ Oxidation state
1+ ion (has 1 more p+ than e- )

12. Ionic Bonds B. Group 2 Alkaline Earth Metals
Lose or transfer 2 electrons
2+ oxidation state
2+ ion (has 2 more p+ than e- )

13. Ionic Bonds
2. Nonmetals
Gain electrons
Form negative ions

14. Ionic Bonds A. Group 16 Oxygen Family Gain 2 electrons
2- oxidation state
2- ion (has 2 more e- than p+ )

15. Ionic Bonds B. Group 17 Halogens Gain 1 electron 1- oxidation state
1- ion (has 1 more e- than p+)

16. Putting it all together…
Group Number
Oxidation Number (ion formed) 1 1+ 2 2+ 13
+3+ 14
4-or 4+ 15 3- 16 2- 17 1-

17. Ionic Bonds
3. Examples: sodium chloride (NaCl), sodium hydroxide (NaOH), calcium fluoride (CaF2), and potassium iodide (KI).

18. Oxidation No. Practice
