  1. Ch. 11 - Chemical Bonds II. Kinds of Chemical Bonds(p.304-308) Ionic Bond Covalent Bond Comparison Chart

  2. A. Ionic Bond • Attraction between 2 oppositely charged ions • Ions - charged atoms • formed by transferring e-from a metal to a nonmetal

  3. NaCl A. Ionic Bond • ions form a 3-D crystal lattice

  4. B. Covalent Bond • Attraction between neutral atoms • formed by sharing e- between two nonmetals

  5. Cl2 H2O NH3 B. Covalent Bond • covalent bonds result in discrete molecules

  6. B. Covalent Bond • Nonpolar Covalent Bond • e- are shared equally • usually identical atoms

  7. - + B. Covalent Bond • Polar Covalent Bond • e- are shared unequally between 2 different atoms • results in partial opposite charges

  8. B. Covalent Bond • Nonpolar • Polar • Ionic View Bonding Animations.

  9. C. Comparison Chart COVALENT IONIC transferred from metal to nonmetal shared between nonmetals Electrons Melting Point high low Soluble in Water yes usually not yes (solution or liquid) Conduct Electricity no molecules, odorous liquids & gases crystal lattice of ions, crystalline solids Other Properties
