Covalent bonds form when two nonmetal atoms share one or more pairs of electrons. Atoms that share electrons in this way form stable molecules. For example, two hydrogen atoms can form a stable H2 molecule by each atom contributing one electron to a shared pair between them. Similarly, two chlorine atoms can form a Cl2 molecule by sharing one pair of electrons, called a single bond. Two oxygen atoms form a particularly strong double bond in an O2 molecule by sharing two electron pairs.

- 2. Covalent Bonds • Covalent bonds occur when atoms share electrons. • Covalent bonds generally form between nonmetals. • Atoms that are covalently bonded form molecules.
- 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
- 6. Chlorine Molecule Let us see how chlorine bonds
- 7. Cl Cl
- 8. Cl Cl
- 9. Cl Cl
- 10. Cl Cl
- 11. Cl Cl octet
- 12. Cl Cl octet
- 13. Cl Cl The octet is achieved by each atom sharing the electron pair in the middle
- 14. Cl Cl The octet is achieved by each atom sharing the electron pair in the middle
- 15. Cl Cl This is the bonding pair
- 16. Cl Cl It is a single bonding pair
- 17. Cl Cl It is called a SINGLE BOND
- 18. Double bond can also be shown as single dash Cl - Cl
- 19. Another example of Single Bond
- 20. Double Bond sometimes simple is better -_-
- 21. Oxygen
- 22. O How will two oxygen atoms bond? O
- 23. O Each atom has two unpaired electrons O

- 26. O O
- 27. O O
- 28. O O
- 29. O O
- 30. O O Oxygen atoms are highly electronegative. So both atoms want to gain two electrons.
- 31. O O Oxygen atoms are highly electronegative. So both atoms want to gain two electrons.

- 34. O O
- 35. O O
- 36. O O Both electron pairs are shared.
- 37. O O 6 valence electrons plus 2 shared electrons = full octet
- 38. O O 6 valence electrons plus 2 shared electrons = full octet
- 39. O O two bonding pairs, making a double bond
- 40. Double bond can also be shown as double dashes
