  6. LET’S FIRST REVIEW IONIC BONDING

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

  10. K F

  11. K F

  12. K F

  13. K F

  14. _ + K F

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

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

  17. Ionic Bonds: One Big Greedy Thief Dog!

  18. So what are covalent bonds?

  19. In covalent bonding, atoms still want to achieve a noble gas configuration (the octet rule).

  20. 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.

  21. 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

  22. Covalent =Sharing

  23. Covalent Bonds

  24. Chlorine forms a covalent bond with itself Cl2

  25. How will two chlorine atoms react? Cl Cl

  26. Cl Cl Each chlorine atom wants to gain one electron to achieve an octet

  27. 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?

  28. Cl Cl

  29. Cl Cl

  30. Cl Cl

  31. Cl Cl

  32. Cl Cl octet

  33. Cl Cl octet circle the electrons for each atom that completes their octets

  34. 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

  35. 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

  36. Cl Cl This is the bonding pair circle the electrons for each atom that completes their octets

  37. Cl Cl It is a single bonding pair circle the electrons for each atom that completes their octets

  38. Cl Cl It is called aSINGLE BOND circle the electrons for each atom that completes their octets

  39. Cl Cl Single bonds are abbreviated with a dash circle the electrons for each atom that completes their octets

  40. Cl Cl This is the chlorine molecule, Cl2 circle the electrons for each atom that completes their octets

  41. O2 Oxygen is also one of the diatomic molecules

  42. O O How will two oxygen atoms bond?

  43. O O Each atom has two unpaired electrons
