The bottom number is the atomic number(Z). 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. Use the following equation to calculate the atomic mass of Bg. Note: Divide the percent abundance of each iso-tope by 100 to obtain its relative Remember that chemical isotopes are atoms that have the same number of protons, but different numbers of neutrons. Thus, chemical isotopes have nearly identical chemicals properties, but some different physical properties. In this investigation, you will determine the relative abundance of the isotopes of pennium and the masses of each isotope. Isotope: an atom of an element with a certain number of neutrons.

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 of 15. Refer to the hydrogen isotopes in Model 1. Each isotope has a special name derived from Latin (protium, deuterium, and tritium). structural feature do these names refer to in the atom?
