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

  2. 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: Edhpop Password: Edhpop1 • http://www.brainpop.com/science/matterandchemistry/chemicalbonds/

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

  4. Bonds Ionic Covalent Loss or Gain of electrons Metal and Non-Metal Share Electrons Only between Non-Metals

  5. Ionic Bonds: One Big Greedy Thief Dog!

  6. Covalent Bonds: SHARE

  7. COVALENT BONDbond formed by the sharingof electrons
