16. The bond length between a carbon atom and an oxygen atom is? a. b.
154 pm
143 pm c. d.
348 kJ/mol
360 kJ/mol
17. As you increase the atomic number of an atom within a period, the length of the bond it forms between a carbon atom: a. b.
Increases
Decreases c. d.
Increases then decreases
Decreases then increases
18. If a carbon atom were to form a bond with Astatine, what would the length of the bond most likely be? a. 126 pm c. 184 pm b. 200 pm d. 225 pm
19. If a carbon atom were to form a bond with Phosphorus, what would the length of the bond most likely be? a. b.
177 pm
190 pm c. d.
165 pm
150 pm

20. As you move down the Halogen Family (it has Fluorine on the top of the column) describe the general trend: a. The bond energy shows a trend of increasing as you move down the family. b. There is a general trend of increasing bond energy as you move down the family. c. bottom.
The bond energy gradually decreases as you move from the top of the family towards the d. There doesn’t seem to be any trend what-so-ever.
21. The bonds found on the table would typically be described as being a. b.
Ionic Bonds
Covalent Bonds c. d.
Transition Ionic Bonds
Male Bonding
22. As you increase the length of an atomic bond, what is the general trend seen? a. As the length of the atomic bond is increased, both atoms get really scared b. c. d.
As the atomic bond length increases, the bond energy typically increases as well
The bond energy typically decreases as the atomic bond length increases
As the atomic bond length increases, the angle between the bonds changes
23. If someone asked you to sign a petition attempting to ban dihydrogen monoxide, what would you say to them? a. b.
That word sounds scary; I’ll sign and give you money too.
Well that one is a no brainer; dihydrogen monoxide is the scientific term for the ionic compound that we call water c. Well that one is also a no brainer because everyone knows that is the technical term for the covalent compound that we call water.
24. Finally, please list all the elements that are found naturally in pairs and draw the Lewis Dot structure of at least one of them.
