Presentation Transcript

  1. Do Now • Which substance contains bonds that involved the transfer of electrons from one atom to another? • CO2 • NH3 • KBr • Cl2 • When sodium and fluorine combine to produce the compound NaF, the ions formed have the same electron configuration as atoms of • argon, only • neon, only • both argon and neon • neither argon nor neon

  2. Ionic Bonding Williamsburg High School for Architecture and Design Mr. Quinn and Ms. Tom 11/13/13

  3. Aim • What happens after an atom steals or loses electrons?

  4. From Yesterday… • All elements want to look like noble gases • They can either gain or lose electrons to get there

  5. Lewis Structures II: The Return

  6. Terminology • Ionic Bond • Valence electrons are transferred • Attraction is electric

  7. Helpful Visuals

  8. Lewis Structures III: The Return II

  9. A&D vs. Regents, Round 1 • An ionic compound is formed when there is a reaction between the elements • strontium and chlorine • hydrogen and chlorine • nitrogen and oxygen • sulfur and oxygen

  10. A&D vs. Regents, Round 3 • Which Lewis electron-dot diagram represents a molecule having an ionic bond?

  11. A&D vs. Regents, Round 2 • The bonds in BaO are best described as • covalent, because valence electrons are shared • covalent, because valence electrons are transferred • ionic, because valence electrons are shared • ionic, because valence electrons are transferred

  12. A&D vs. Regents, Round 4 • Which Lewis electron-dot diagram represents calcium oxide?

  13. A&D vs. Regents, Round 5 • Which element forms an ionic compound when it reacts with lithium? • K • Fe • Kr • Br
