In the fictional element "Pennium," the atom is represented by a United States penny. In the real world, a penny is a penny; you spend it, you find it, and it generally looks the same. However, chemically, the penny has not been consistent over time. isotopes of pennium lab answer key

Use the formula: (Average mass of isotope 1 × % abundance as decimal) + (Average mass of isotope 2 × % abundance as decimal) The atomic mass of Pennium is not a simple average of 3

= (3.106 × 0.50) + (2.501 × 0.50) = 1.553 + 1.2505 = (atomic mass of Penmium) However, chemically, the penny has not been consistent
