Atoms and the Periodic Table

Atoms and the Periodic Table. Chapter 4 . Atomic Structure. Atoms are the simplest unit of a substance that still maintain the properties of the substance. John Dalton proposed that atoms could not be divided. Dalton also stated that atoms of different elements could join to form compounds.
