ISOTOPES: DETERMINING ATOMIC MASS. EXPERIMENT 4. NOTE: You do not need to do a regular lab report and coversheet. Complete this lab sheet and 

NOTE: All atoms of an element are isotopes of that element. Most elements have 1, 2 or 3 naturally occurring isotopes. This means that in any sample of the element these naturally occurring isotopes are all present typically always in the same % ratio. For example: The isotope Cu-63 has the percent abundance of 75% and the isotope Cu-65 has the percent abundance of 25%. 7. The atomic mass of copper is not exactly equal to 64, midway between the mass numbers of copper-63 and copper-65 because the percent abundances of the two are not 50% and 50% so the atomic mass is not going to be exactly in the middle GS104 Lab 8 Answer Key - Geological Time Pre-Lab Questions 1. stratigraphy - study of spatial and temporal relationships between layers of sedimentary rock.

Answers to Discussion Questions (Student answers will vary.) 1. The atomic mass of the “bean bag” element (Bg) represents a weighted average of the mass of each isotope and its relative abundance.

They each have 6 protons (atomic # = 6), but one As in real elements, these isotopes have different masses. Your job will be to obtain a sample of vegium and determine the mass and relative abundance of each isotope. Unlike real isotopes, the particles in this lab do differ slightly in mass from one another, so you will first determine the average mass of each type of isotopic particle.
