Understanding Ionic Bonding and Electron Transfer in Compounds

This educational content explores the fundamentals of ionic bonding, focusing on the transfer of electrons between atoms. Students will learn about the characteristics of ionic compounds, such as those formed from sodium and fluorine (NaF), and how these compounds achieve noble gas electron configurations like those of argon and neon. The lesson includes discussions on Lewis structures, reactions between different elements to form ionic bonds, and the characteristics that differentiate ionic and covalent bonds. Engaging visuals and examples enhance comprehension.

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
