On a separate piece of paper…
10. List the mechanism behind covalent bonds. What are the properties of covalent bonds? How does the bonding
mechanism give us those properties?
11. List the mechanism behind ionic bonds. What are the properties of covalent bonds? How does the bonding
mechanism give us those properties?
12. List the mechanism behind metallic bonds. What are the properties of covalent bonds? How does the bonding
mechanism give us those properties?
13. Using the internet, find 10 compounds you use every day (use Wikipedia to find the chemical formula of
everyday substances). Write the name, chemical formula and draw the Lewis Dot Structure.
