elements likely to form covalent bonds?
3. What goal do atoms have when they are forming covalent bonds? How do they
reach this goal?
4. What rule to atoms follow when forming covalent bonds? What are the
exceptions?
5. What is the unit structure of covalent compounds?
6. Why are covalent compounds more likely to form liquids or gases than ionic
compounds are?

7. When elements form covalent bonds, electrons are shared. Watch the video of
the sharing between hydrogen atoms. A similar electron sharing occurs between
chlorine and fluorine as follows:
◙ ◙
◙ ◙
•••
◙
◙
• Cl
• •••
◙ → • Cl ◙ F ◙
• •• + ◙ F
◙ ◙
•• ◙◙
For the following problems, draw the Lewis dot structures and show the
electrons sharing between the atoms.
a. Sulfur and oxygen (SO)
b. Selenium and bromine (SeBr2)
c. Carbon and oxygen (CO)
8. What different types of covalent bonding are there? What is the deciding factor
in determining which type of covalent bonding is present?
9. In the type of covalent bonding present in water molecules, what induces a
dipole? How is it represented in a drawing of the molecule? Show the
representation for water and label the parts.
