Rust-compound Air-mixture Helium-element soil-mixture Sea water-mixture salt-compound An element is made of a single pure substance, matter-Helium, hydrogen, etc. A compound is a pure substance made of elements chemically put together. Not easily separated.
A water molecule is not three separate atoms, two hydrogen (H) and one oxygen (O), but it is actually a unique H 2 O molecule with its own set of distinct properties. Like elements that are formed of atoms of the same sort, compounds are formed of molecules of the same sort.
