Covalent bonding masha ld (201127636)

  1. 1. Covalent Bond Covalent Bond Covalent Bond Covalent Bond Covalent Bonding Grade 10 Covalent Bond Covalent Bond Covalent Bond by Masha LD 201127636 Covalent Bond
  2. 2. Covalent Bonds • Covalent bonds occur when atoms share electrons. • Covalent bonds generally form between nonmetals. • Atoms that are covalently bonded form molecules.
  3. 3. This involves the sharing of electrons by 2 or more atoms. The electrons are shared, not taken as with ionic bonds. EXAMPLES INCLUDE THE BONDS BETWEEN: H2 F2 Br2 Cl2 HCl H 2O
  4. 4. H x O H Another example : Hydrogen H H
  5. 5. Chlorine Molecule Let us see how chlorine bonds
  6. 6. Cl Cl
  7. 7. Cl Cl
  8. 8. Cl Cl
  9. 9. Cl Cl
  10. 10. Cl Cl octet
  11. 11. Cl Cl octet
  12. 12. Cl Cl The octet is achieved by each atom sharing the electron pair in the middle
  13. 13. Cl Cl The octet is achieved by each atom sharing the electron pair in the middle
  14. 14. Cl Cl This is the bonding pair
  15. 15. Cl Cl It is a single bonding pair
  16. 16. Cl Cl It is called a SINGLE BOND
  17. 17. Double bond can also be shown as single dash Cl - Cl
  18. 18. Another example of Single Bond
  19. 19. Double Bond sometimes simple is better -_-
  20. 20. Oxygen
  21. 21. O How will two oxygen atoms bond? O
  22. 22. O Each atom has two unpaired electrons O
  23. 23. O O
  24. 24. O O
  25. 25. O O
  26. 26. O O
  27. 27. O O
  28. 28. O O
  29. 29. O O Oxygen atoms are highly electronegative. So both atoms want to gain two electrons.
  30. 30. O O Oxygen atoms are highly electronegative. So both atoms want to gain two electrons.
  31. 31. O O
  32. 32. O O
  33. 33. O O
  34. 34. O O
  35. 35. O O Both electron pairs are shared.
  36. 36. O O 6 valence electrons plus 2 shared electrons = full octet
  37. 37. O O 6 valence electrons plus 2 shared electrons = full octet
  38. 38. O O two bonding pairs, making a double bond
  39. 39. Double bond can also be shown as double dashes
