The periodic table of elements includes only elements.

Explanation:

All the materials on Earth are made up of the same elements, which can be found on the periodic table. These elements combine to form compounds, or mixtures such as water, a compound of hydrogen and oxygen, or air, which is a mixture of nitrogen, oxygen, carbon dioxide (a compound!) and many other gases, even water vapor. It is the combination of these elements in different ways that gives us so many different substances. Hope this helps!

Elements are pure substances with only one type of atom.

The substances on Earth are created when two or more elements are combined.

Because elements can combine to form compounds, more substances can be created on Earth.
