1 The Elements of the Periodic Table

2 NAME MORE EXAMPLES OF ELEMENTS FOUND IN NATURE…
A pure substance that cannot be broken down into different substances. For example, the pure OXYGEN in an oxygen tank. NAME MORE EXAMPLES OF ELEMENTS FOUND IN NATURE…

3 NAME MORE EXAMPLES OF COMPOUNDS FOUND IN NATURE…
A substance that is made from two or more elements that are chemically bound together. For example: water (H2O). No matter how much you look at the periodic table, you won’t find water on there. That’s because water is a compound molecule made from the elements hydrogen (2) and oxygen (1). NAME MORE EXAMPLES OF COMPOUNDS FOUND IN NATURE…

4 Mixtures Mixtures are combinations of two or more substances in which each substance retains its own chemical identity. Contains different elements, but, unlike a compound, are not chemically bonded.

5 Which are pure substances and which are mixtures?
