      Yup. Pretty much every element in the periodic table has a different density (if it’s a solid or liquid). In addition there are elements like carbon, which have different allotropes, (i.e. Graphite, Diamond, Charcoal) and each of these can have different densities. On top of that, you can mix and react different elements together to form new compounds and mixtures, and all of these can have different densities.
