ISOTOPES
1. What does the atomic number tell you about an element?
2. Draw a picture of a Lithium atom that illustrates your answer to question #1.
3. List the atomic number for each of the following elements (use your periodic table):
Carbon
Oxygen
Hydrogen
Calcium
Gold
Uranium
4. Explain what the mass number tells you about an atom.
5. What is an atomic mass unit (amu)?
Use table 4.3 on page 114 in the textbook for the following questions:
6. To the best of your ability, draw the 2 isotope of carbon, the 3 isotope of oxygen, and the 4 isotopes of sulfur from table 4.3.
Your pictures should show the protons and neutrons in the nucleus and the electrons.
7. What is and isotope?
8. Which isotope of oxygen is most common? What does that mean?
9. How does the fact that each isotope has a different percent abundance affect the atomic mass?
10. Calculate the atomic mass of Chlorine. The two isotopes of Chlorine have atomic masses of 34.969 amu and 36.966 amu. The
relative abundance of the first is 75.77% and of the second is 24.23%.
