Use Critical Thinking: Use the information in the chart and your notes to answer the following questions. Use complete sentences.

1. The atomic masses given in this chart are whole numbers. How are the atomic masses in the periodic table different and why?

2. If the atomic mass of an element can vary, how is more than one mass accounted for in the periodic table? Give an example.

3. Electrons are so small that they don’t factor into the atomic mass of an atom. Yet, they account for most of an atom’s volume. Explain why this is so.
