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.
The atomic no., #Z#, defines the number of protons, and hence the identity of the atom. Explanation: Aluminum has (by definition) 13 protons, 13 positively charged particles. Because aluminum is neutral (as is all matter), it therefore has 13 negatively charged particles, electrons. Aluminum has an atomic mass of about 27 amu; how many neutrons are present in the aluminum nucleus?
