Suppose we have 20 pennies with 10 heads and 10 tails. isotopes of pennium lab answer key

In the "Isotopes of Pennium Lab," students use pennies to simulate isotopes of an element. The lab involves counting the number of "heads" and "tails" on a set of pennies, which represent the protons and neutrons in an atom. The pennies are used to model the different isotopes of an element, and students calculate the atomic mass of each isotope. | Isotope | Mass (u) | Number of

: The average atomic mass of the element Pennium was found to be 2.744 g. This value is closer to the mass of the post-1982 isotope (2.50 g) because post-1982 pennies had a higher relative abundance (60%) than pre-1982 pennies (40%). This lab successfully models how isotopic masses and abundances determine an element’s average atomic mass on the periodic table. The pennies are used to model the different
