Presentation Transcript

  1. Objectives • I can compare the properties of ionic and covalent compounds with a Venn diagram. • I can practice drawing Lewis Dot Diagrams of molecules by completing a worksheet. • I can investigate the relationship between electronegativity and chemical bonding by sorting compounds by electronegativity data.

  2. Ionic vs. Covalent Bonds • Bond Strength = the energy needed to break the bonds between atoms in a compound.

  3. Ionic vs. Covalent Bonds

  4. Ionic vs. Covalent Bonds

  5. Ionic vs. Covalent Bonds Water (H2O) molecules Lithium Chloride (LiCl) crystal lattice

  6. Ionic vs. Covalent Bonds

  7. Ionic vs. Covalent Bonds

  8. Ionic vs. Covalent Bonds

  9. Ionic vs. Covalent • Think, Pair, Share: With a partner, fill in the middle overlapping portion of the Venn diagram. What do ionic and covalent compounds have in common? • Possible answers: • types of compounds, formed by chemical bonds, include more than one atom, involve electrons, are formed and broken by chemical reaction

  10. Chemistry of Life • All organisms (living things) are made of macromolecules. • Macromolecules are large covalent compounds. • The atoms in proteins, carbohydrates, nucleic acids, and lipids are all connected by covalent bonds.

  11. 3 Types of Bonding
