​Mass Number vs. Average Atomic Mass

​•We will cover this more in our lesson tomorrow

•Basically:   Average Atomic Mass looks at all the variations of an atom known as isotopes and averages their masses based on how abundant they are here on earth.

•The periodic table shows a decimal number for Average Atomic Mass because it is an average

•The mass of an atom is made up of protons & neutrons, so we can use this number (rounded to a whole number) to calculate protons and neutrons
