Beanium Isotope

10/6/11-10/10/1
I. INTRODUCTION:
1) Purpose:
In this lab I carried out experiments and performed the necessary calculations to determine the atomic mass of the fictitious element Beanium. These experiments and calculations are equivalent to the way scientists actually determine the atomic mass of elements. The six different isotopes of Beanium are black eyed, black, kernels, white, brown, and spotted brown. As in real elements, the mixture of isotopes are collections of atoms of the element each having different masses because they have different numbers of neutron. My job was to obtain a sample of Beanium with all six of its representative isotopes, and determine the relative abundance of each isotope. From this data I had to calculate the average mass of each isotope and the weighted average atomic mass of the element Beanium. Unlike real isotopes, the individual isotopic particles of Beanium differ slightly in mass, so I had to determine the average mass of each type of isotopic particle. Then calculate the "weighted average atomic mass" of Beanium.
2) Lab Report: I had to complete the lab and begin to write my own lab report in class – one per student – NO GROUPS! My s lab report will have, labeled with roman numerals: I Introduction Section, II procedure Section, III Data Table/ Calculations Section, and V a conclusion section.
3) What is an isotope: form of element with same atomic number: each of two or more forms of a chemical element with the same atomic number but different numbers of neutrons.
II. PROCEDURE:
1) Obtain a sample of the Beanium “atoms” in a cup from the bag
2) Separate your beans by color.
3) Count the number of each color of bean. Record on data table.
4) Weigh all the black beans. Record mass on data table. Do the same with all
5) Mass the total in each group
6) Place all the beans back in the container at the front of the room.
