This document discusses the classification of matter. It explains that matter can be classified as either pure substances or mixtures. Pure substances are further classified as elements or compounds. Elements are the simplest type of substance and consist of only one type of atom, with each element having unique physical and chemical properties. Atoms of different elements can also combine to form compounds with unique properties, such as hydrogen and oxygen atoms combining to form the compound water.

chemical properties.

5. Example
Iron- a metallic solid, conductor of
electricity, attracted by a magnet, and
reacts with oxygen
Oxygen- a colorless, odorless, and
tasteless gas, reacts with iron

8. Atoms of different
elements can combine to
form compounds.
Hydrogen(H)+oxygen(O)=water H2O
