Covalent bonds form when atoms share electrons to achieve a stable outer electron configuration. Nonpolar covalent bonds occur when atoms share electrons equally, while polar covalent bonds form when electrons are shared unequally between atoms of different electronegativity. The document discusses how to explain and illustrate the formation of covalent bonds through examples of nonpolar and polar covalent bonds.

1. Daily task:Explain and illustrate
the formation of covalent
bonds.

2. Do you share what you have with your
classmate?

3. Essential Question: How covalent bonding
takes place?

13. Non POLAR
COVALENT BOND
EN diff= 0.4 or less
POLAR COVALENT
BOND
EN diff= greater than
0.4 but less than 1.9
