4. What is an isotope?

Pitanje 5

5.

5. In words, describe how to find an average.

Pitanje 8

8.

Calculate the percent abundance of isotope #1. To do this, divide the total number of atoms for
isotope #1 by the total number of atoms of all isotopes. Multiply by 100 to get a percent. Show all
work.

Pitanje 9

9.

Calculate the percent abundance of isotope #2. Show all work.

Pitanje 10

10.

Calculate the percent abundance of isotope #3. Show all work.

Pitanje 11

11.

Based on the percent abundance, which isotope is most abundant? Explain.

Pitanje 12

12.

Why isn’t the atomic mass of most of the elements on the Periodic Table a whole number?

Pitanje 13

13.

Which number in the data chart is the average atomic mass for the element Beanium? Show the calculation you used to figure out the answer.

Pitanje 14

14.

If the heaviest isotope was more abundant, and the other two isotopes were less abundant, what would happen to the average atomic mass of Beanium? Explain.

Pitanje 15

15.

Use the Periodic Table to write an example of two isotopes of one element.

Pitanje 16

16.

Which of your two isotopes from question 15 is more abundant? Explain.
