Chemistry is the study of matter and the changes it undergoes. All matter is made up of basic building blocks alled atoms. Atoms are the smallest divisions of matter that can be isolated through physical or chemical
methods. A large collection of the same type of atom is called an ELEMENT. Elements are different from one
another because their atoms contain different numbers and kinds of subatomic particles, protons, neutrons, and
electrons. All known elements are listed on the Periodic Table.
