Bohr Models of Isotopes Activity
Name:__________________________
Period:______
In this lab, we will make models of various isotopes. Then, we will circle the more abundant isotope which is always the
one that is closest to the average mass on the periodic table. This average mass is also called the atomic mass.
Model of carbon 12 with Kit
Then make model of carbon 14 with kit
Model of Carbon Atoms we will Draw
using colored pencils.
Carbon – 12
Carbon - 14
Now, try these. Be sure to make the models before you make your simplified diagrams. Remember to circle the more
abundant isotope for each element.
Argon - 39
lithium - 6
boron - 10
sulfur - 32
Calcium - 40
