AVERAGE ATOMIC MASS LAB
“BEANIUM”

PURPOSE: 
1. Identify the number of Beanium isotopes
2. Determine the mass of each isotope
3. Find the percent abundance of each isotope
4. Calculate the average atomic mass of Beanium

EQUIPMENT:  
Scale
Sample of Beanium
Calculator

Procedure:
Analyze your individual sample of Beanium to complete the following data table. (Also, you are NOT allowed to consider the mass of the entire sample in solving this problem, as the sample tends to rapidly oxidize, lose electrons, and explode when all isotopes are placed on a balance together.)

Fill in table OR upload your data.

Calculate the average atomic mass of your Beanuim. Show your work.

Required

The element Silicon (Si) has three stable isotopes with the following masses and abundances:

Calculate the average atomic mass of magnesium from this data. Don't forget to show work and units.

Required

An element is a mixture of two isotopes. One isotope has an atomic mass of 34.969 amu and an abundance of 64.88%. The other isotope has an atomic mass 36.966 amu. Create a data table for this element like the one shown in #3. Calculate the average atomic mass of the element, and then use your periodic table to identify the element.

Required

Reflect on all that you have done in this lab activity and briefly explain why the atomic mass reported for each element on the periodic table is not a whole number.

1.5

If the heaviest isotope was more abundant, and the other two isotopes were less abundant, what would happen to the atomic weight of beanium? Why?

Required

2.5

Because isotopes have identical chemical properties, radioactive isotopes can be used for medical use. Based on where the following elements are likely found in the body, match each radioisotope with its medical use.

Draggable item		Corresponding Item
Calcium-47		measure extracellular fluid

Required

Write a conclusion to this lab in which you: restate the purpose, summarize your procedure and data recorded, explain the math, and finally give your results. Also, in your conclusion, explain the concept of a weighted average, and how it applies to the determination of the average atomic mass of the elements on the Periodic Table.

Remember, here is a great guide for writing your conclusion:
1) Restate the purpose
2) Summarize the procedure and data collection
3) Discuss any important principles / equations used
4) Explain the graphs and/or math
5) Report your results

Also, please include any other interesting information you would like to add.

Draggable item		Corresponding Item
Calcium-47		measure extracellular fluid
Phosphorus- 32		study of bone formation
Iodine-131		diagnose thyroid disorders
Iron-55		red blood cell studies
Sodium-24		genetic (DNA) research
