Cl – Sodium chloride) following elements: H, C, N, O, Cl 3) For each of the elements above, write Molecular compounds are made up of down how many pairs of electrons there only nonmetals. are and how many unpaired electrons there are. 2
Rules for Naming Covalent Compounds • First, need to recognize that it is a covalent compound. • How do we do that? ? Covalent compounds should only contain nonmetals!
Rules for Naming Covalent Compounds Similar to ionic compound naming • Name the first element that comes first • The second element drops the ending and adds –ide BUT! • The names need prefixes.
Rules for Naming Covalent Compounds • CO vs. CO 2 CO would be carbon monoxide CO 2 would be carbon dioxide • Both elements need prefixes EXCEPT when there is only one of the first element.

Debrief DIHYDROGEN MONOXIDE (DHMO) -Can be found all around the world. -The U. S. uses about 346, 000 million gallons every day.
Debrief DIHYDROGEN MONOXIDE (DHMO) Pros -Is found in the human body. - It can be used as a coolant. -Plant and animal life need it to live. -It is a necessary ingredient in many foods and almost all beverages.
Debrief DIHYDROGEN MONOXIDE (DHMO) Cons -The major component of acid rain. -Contributes to the Greenhouse Effect. -May cause severe burns. -May cause electrical failures and decreased effectiveness of automobile brakes.
Debrief - On a separate sheet of paper, answer: - Based on what you learned today about naming molecular compounds and dihydrogen monoxide, do you think it should be banned? Why or why not? - DON’T FORGET YOUR NAME!
