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

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?

23. O
Each atom has two unpaired electrons

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
