Aluminum has a density of 2.7 grams per milliliter. An element in the boron group, aluminum is a very light metal, but it is dense enough to sink in water. It is the third most abundant element in the Earthâs crust and is the most abundant metal overall.
All aluminum atoms have 13 protons. However, all aluminum-27 atoms have an atomic mass of 27, which means the number of neutrons + protons = 27, and since all aluminum atoms have 13 protons, all aluminum-27 atoms must have 14 neutrons (because protons + neutrons = 27 ---> 13 + 14 = 27).
