CH 8 Worksheet for Carbon Chemistry

 1.    How many bonds can Carbon make?    Four

2.    How many Valence electrons does Carbon have? _4_ Where are the other 2 electrons?  They are in the first level, closer to the nucleus

3.    Is water an organic molecule?  No  (it does not contain carbon)

4.    Name 2 products that are made entirely of Carbon: diamonds and graphite (for pencils)

5.    Where can we find one of these products in our classroom?  In Mrs. Tiday's ring or in a student's pencil.

6.    What is the difference in how their Carbon atoms are arranged?  

• In diamonds, the carbon molecules are bonded with 4 other carbons and form a three dimensional structure that is very strong.
•  In graphite, the carbon atoms join with 3 other carbons to form sheets.   The sheets are stacked and flake off when you write with the pencil.

7.    What is the difference between a compound and a molecule?   

• A molecule is a more general term.  It refers to any group of bonded atoms whether they are the same element or different elements.  
• A Compounds is a group of bonded atoms that includes at least 2 different elements from the Periodic Table
• Examples:  02 is a molecule, but not a compound.  CO2 is a molecule and a compound because it contains 2 elements

8.    Name three characteristics of organic molecules: 

• they have an ordor
• they contain carbon
• they have low boiling and melting points
• they are not good conductors 
• they do not dissolve well in water

9.   Why are Nucleic Acids NOT listed on the pie chart?  They are found in everything that has cells so it is automatically included in the other sections such as proteins.
