Name Period Date Lab Beanium Isotope Lab Introduction Isotopes are atoms of the same chemical element, each having a different mass number (different number of neutrons). Isotopes differ in mass number but never in atomic number (# of protons). Since we cannot see atoms, you will use beans to represent atoms. The purpose of this lab is to calculate the average atomic mass using beans, and to observe the difference between isotopes. 1. The mass number of the atom is the total number of & 2. Isotopes are different types of atoms of the same element, but with a different number of 3. Carbon-13 is an isotope of Carbon with a mass number of 13. How many neutrons are in Carbon-13? Refer to this picture of an atom’s nucleus to answer questions 4-9. 4. How many protons? 5. What is the atomic #? 6. What element is this? 7. How many neutrons? 8. What is the mass #? 9. What is the isotope name? Procedure 1. Each group of 3 will get 1 small cup of lima beans and 1 small cup of cranberry beans. 2. Count the number of lima beans in your cup and record this number in the data table below. Repeat this step for the cranberry beans (cran beans). 3. Using a the weigh boat, measure the total mass of your plain lima beans and record this number in the data table. Repeat this step for the cran beans. ***REMEMBER to ZERO out the weigh boat DATA TABLE: Number of beans Mass of beans Isotope #1 - Lima beans Isotope #2 - Cran beans Total Number of all your beans
