Once the calculations have been performed, students answer a short analysis questions that asks them to calculate how the average atomic mass changes when one isotope increases in quantity in the sample. The measured result is then reported as: - Atomic mass = Average atomic mass ± Average deviation. This experiment is originated from the "Bag O'Isotopes", [1-3] in which small numbers of "isotopes" (e. g., 8 large lime beans, 11 baby lime beans, and 15 black-eyed peas with given atomic numbers) are presented to students and they count all of the isotopes to find the atomic mass of element "legumium". Copyright © 2018 Scientific & Academic Publishing. Isotope bean lab answer key image. You are on page 1. of 3. Student activity sheet (per student or per group).
