Lisa studied the models of three carbon nuclei shown below.
She listed information about the carbon nuclei in a table.
Name Carbon 12 number of protons 6 number of neutrons 6.
Name Carbon 13 number of protons 6 number of neutrons 7.
Name Carbon 14 number of protons 6 number of neutrons 8
How should lisa title the table?
A. Carbon Bond Types
B. Carbon Isotopes
C. The Carbon Cycle
D. Chemical Reactions
Is the answer A?

  1. If the answer is A, what bond types do you think it shows? The bond types I know about are ionic, covalent, polar covalent, etc. How would this fit in with your answer?
    Second question, What differences do you see in the three carbons?

  2. The differences I see is that the neutrons add 1 doe each carbon.

  3. So the protons are the same (at 6 each) but neutrons are not (6,7,8). What do you call atoms that have the same atomic number(number of protons at 6) but different mass numbers (12, 13, 14) which is the same thing as saying the same number of protons but different number of neutrons?
