Yesterday,
we did an activity to further our understanding on isotopes. Isotopes are atoms
that belong to the same element, but the number of neutrons varies
causing the atomic mass to vary between the different isotopes. This was
demonstrated using different colored beans to represent the isotopes of the
fictional element “beanium”. We sorted all of the beans by color and found the
average mass of each individual bean for that specific color. Not surprisingly,
each color had a different average mass, much like the isotopes of an element.
We used these numbers and percent of abundance to find the average atomic mass
of beanium. The picture shows all of our beans sorted by color.
