  3. LET’S FIRST REVIEW IONIC BONDING Chem-160

  4. K F In an IONIC bond, electrons are lost or gained, resulting in the formation of IONS in ionic compounds. Chem-160

  5. K F Chem-160

  6. K F Chem-160

  7. K F Chem-160

  8. K F Chem-160

  9. K F Chem-160

  10. K F Chem-160

  11. _ + K F Chem-160

  12. _ + K F The compound potassium fluoride consists of potassium (K+) ions and fluoride (F-) ions Chem-160

  13. _ + K F The ionic bond is the attraction between the positive K+ ion and the negative F- ion Chem-160

  14. So what are covalent bonds? Chem-160

  15. In covalent bonding, atoms still want to achieve a noble gas configuration (the octet rule). Chem-160

  16. In covalent bonding, atoms still want to achieve a noble gas configuration (the octet rule). But rather than losing or gaining electrons, atoms now share an electron pair. Chem-160

  17. In covalent bonding, atoms still want to achieve a noble gas configuration (the octet rule). But rather than losing or gaining electrons, atoms now share an electron pair. The shared electron pair is called a bonding pair Chem-160

  18. Chlorine forms a covalent bond with itself Cl2 Chem-160

  19. How will two chlorine atoms react? Cl Cl Chem-160

  20. Cl Cl Each chlorine atom wants to gain one electron to achieve an octet Chem-160

  21. Cl Cl Neither atom will give up an electron – chlorine is highly electronegative. What’s the solution –what can they do to achieve an octet? Chem-160

  22. Cl Cl Chem-160

  23. Cl Cl Chem-160

  24. Cl Cl Chem-160

  25. Cl Cl Chem-160

  26. Cl Cl octet Chem-160

  27. Cl Cl octet circle the electrons for each atom that completes their octets Chem-160

  28. Cl Cl The octet is achieved by each atom sharing the electron pair in the middle circle the electrons for each atom that completes their octets Chem-160

  29. Cl Cl The octet is achieved by each atom sharing the electron pair in the middle circle the electrons for each atom that completes their octets Chem-160

  30. Cl Cl This is the bonding pair circle the electrons for each atom that completes their octets Chem-160

  31. Cl Cl It is a single bonding pair circle the electrons for each atom that completes their octets Chem-160

  32. Cl Cl It is called aSINGLE BOND circle the electrons for each atom that completes their octets Chem-160

  33. Cl Cl Single bonds are abbreviated with a dash circle the electrons for each atom that completes their octets Chem-160

  34. Cl Cl This is the chlorine molecule, Cl2 circle the electrons for each atom that completes their octets Chem-160

  35. O2 Oxygen is also one of the diatomic molecules Chem-160

  36. O O How will two oxygen atoms bond? Chem-160

  37. O O Each atom has two unpaired electrons Chem-160

  38. O O Chem-160

  39. O O Chem-160

  40. O O Chem-160

  41. O O Chem-160

  42. O O Chem-160

  43. O O Chem-160

  44. O O Oxygen atoms are highly electronegative. So both atoms want to gain two electrons. Chem-160

  45. O O Oxygen atoms are highly electronegative. So both atoms want to gain two electrons. Chem-160

  46. O O Chem-160

  47. O O Chem-160

  48. O O Chem-160

  49. O O Chem-160

  50. O O Both electron pairs are shared. Chem-160
