Atomic Bonding Korey Tremblay Chemistry
Review Protons and Electrons Nucleus Orbitals Atomic Radius
Goals Ability to answer questions about: Electronegativity Lewis Dot Diagrams Different types of Bonding
Electronegativity Atomic radius Electronegativity number
Examples Sodium Chloride – NaCl Magnesium Bromide – MgBr2
Examples Sodium Chloride – NaCl Magnesium Bromide – MgBr2 Notice something about these examples?
Ionic compounds “Stealing” of electrons Metal and Nonmetal Electronegativity difference Octet rule
Lewis Diagrams – Ionic compounds Electrons belong only to one atom Each atom is charged Lewis diagram of Water Salt experiment
Covalent bonds Both atoms “share” the electrons Forms a stronger bond Octet rule Oxygen
Lewis Diagrams – Covalent bond Drawing a Lewis Diagram for O2 Partial Charges (water) Hydrogen bonds
Hydrogen Bonding Based on attraction of charges No electrons are shared or transferred Penny drop experiment
Next week… VSEPR Like charges repel
