  2. Section 1 Introduction to Chemical Bonding Chapter 6 Section 1 Intro to Chem Bonding pages 175-177

  3. Chapter Vocabulary Chemical bond Ionic bonding Covalent bonding Nonpolar covalent bond Polar Polar covalent bond Chapter 6 Section 1 Intro to Chem Bonding pages 175-177

  4. Types of Chemical Bonding • Chemical Bond – a mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together. Chapter 6 Section 1 Intro to Chem Bonding pages 175-177

  5. Types of Chemical Bonding • Ionic Bonding – a bond that results from the electrical attraction between cations and anions p. 176 Chapter 6 Section 1 Intro to Chem Bonding pages 175-177

  6. Ionic Bonding p. xx Chapter 6 Section 1 Intro to Chem Bonding pages 175-177

  7. Types of Chemical Bonding • Covalent Bonding – results from the sharing of electron pairs between atoms p. 176 Chapter 6 Section 1 Intro to Chem Bonding pages 175-177

  8. Covalent Bonding p. xx Chapter 6 Section 1 Intro to Chem Bonding pages 175-177

  9. Ionic or Covalent? The type of bond can be estimated by calculating the difference in the elements’ electronegativity. Chapter 6 Section 1 Intro to Chem Bonding pages 175-177

  10. Electronegativities on Page 161 p. 161 Chapter 6 Section 1 Intro to Chem Bonding pages 175-177

  11. Type of Bond HCl H = 2.1 Cl = 3.0 3.0 – 2.1 = 0.9 Polar Covalent H2 H = 2.1 2.1 - 2.1 = 0 Nonpolar Covalent Chapter 6 Section 1 Intro to Chem Bonding pages 175-177

  12. Electronegative Differences p. xx Chapter 6 Section 1 Intro to Chem Bonding pages 175-177

  13. Practice Problems Find the type of bond of the following… • H2S • Cs2S • SCl6 • NCl3 p.177 1. PC 2. I 3. PC 4. NPC Chapter 6 Section 1 Intro to Chem Bonding pages 175-177

  14. Polar and Nonpolar • Nonpolar Covalent • Electrons are shared equally by the bonded atoms • Balanced distribution of charge Chapter 6 Section 1 Intro to Chem Bonding pages 175-177

  15. Polar and Nonpolar • Polar Covalent • Electrons are shared equally by the bonded atoms because of the atom unequal attraction • Uneven distribution of charge Chapter 6 Section 1 Intro to Chem Bonding pages 175-177

  16. What is it? p. xx Chapter 6 Section 1 Intro to Chem Bonding pages 175-177

  17. Electron Dot Diagrams • Shows the valence electrons as dots around the symbol Cl Li Al Chapter 6 Section 1 Intro to Chem Bonding pages 175-177

  18. Electron Dot Diagram p. xx Chapter 6 Section 1 Intro to Chem Bonding pages 175-177
