151 has an abundance of 48.03% and Europium-153 has an abundance of 51.97%. What is the atomic mass of europium? 4. An element consists of four isotopes with masses of 84 (abundance 0.50%), 86 (abundance of 9.9%), 87 (abundance of 7.0%), and 88 (abundance of 82.6%). Calculate the atomic mass of the element. What is the elément? 4. Boron exists in two isotopes, boron-10 and boron-11. Based on the atomic mass, which isotope should be more abundant? 5. lodine is 80% 1271, 17% 1261, and 3% 128I. Calculate the average atomic mass of iodine. 6. Rubidium is a soft, silvery-white metal that has two common isotopes, "Rb and ""Rb. Using the average mass from the periodic table, determine the percent abundance of each isotope.
