  1. Atomic Bonding Korey Tremblay Chemistry

  2. Review Protons and Electrons Nucleus Orbitals Atomic Radius

  3. Goals Ability to answer questions about: Electronegativity Lewis Dot Diagrams Different types of Bonding

  4. Electronegativity Atomic radius Electronegativity number

  5. Examples Sodium Chloride – NaCl Magnesium Bromide – MgBr2

  6. Examples Sodium Chloride – NaCl Magnesium Bromide – MgBr2 Notice something about these examples?

  7. Ionic compounds “Stealing” of electrons Metal and Nonmetal Electronegativity difference Octet rule

  8. Lewis Diagrams – Ionic compounds Electrons belong only to one atom Each atom is charged Lewis diagram of Water Salt experiment

  9. Covalent bonds Both atoms “share” the electrons Forms a stronger bond Octet rule Oxygen

  10. Lewis Diagrams – Covalent bond Drawing a Lewis Diagram for O2 Partial Charges (water) Hydrogen bonds

  11. Hydrogen Bonding Based on attraction of charges No electrons are shared or transferred Penny drop experiment

  12. Worksheet!

  13. Next week… VSEPR Like charges repel
