You may have noticed on the periodic table that the atomic mass of an element is usually not a whole number. That happens because of isotopes. An atom that is missing a neutron or has an extra neutron is called an isotope. They are still the same element; however, they are just a little different from every other atom of the same element.…

The purpose of this investigation was to find the average atomic mass for the element Beanium with three isotopes. The average atomic mass is the average mass of the atoms of the element divided by the total number of atoms. An isotope is an atom with the same number of protons, but different number of neutrons; they are different forms of a single element. Since we knew the isotopes had almost the same amount of sub-atomic particles, we made our hypothesis the following: If the sub-atomic particles are almost exact in amount the total mass, average mass, relative abundance, percent abundance, and the relative mass were also going to be almost exact.…
