2. 10 TH GRADE ATC LESSON NOVEMBER 8, 2011 Covalent Bonds

3. Teachers Show “BrainPop” video on Bonding. All chemistry students are learning about Ionic and Covalent Bonding in their Chemistry classes. They have been exposed to the concept and ARE able to complete the lesson. Video is located at Brainpop.com Username: EdhpopPassword: Edhpop1 http://www.brainpop.com/science/matterandchemistry/chemicalbonds/

4. Essential Question How can the periodic table be used to predict bonds?

5. Bonds IonicCovalent Loss or Gain of electrons Metal and Non-Metal Share Electrons Only between Non-Metals

6. Ionic Bonds: One Big Greedy Thief Dog!

7. Covalent Bonds: SHARE

8. COVALENT BOND bond formed by the sharing of electrons

10. Covalent bonding CCl 4 - Covalent C Cl HCl - Covalent H Cl H 2 O - Covalent H O H NH 3 - Covalent H N H H NaCl - Ionic [ Cl ] – [Na] + OH – - Covalent O H H 2 - Covalent HH For more lessons, visit www.chalkbored.com www.chalkbored.com
