The atomic theory is a scientific description of the nature of atoms and matter.
The Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties.
After years of studying Chemical reactions, Dalton was able to accurately determine the mass ratios of the elements involved in the reactions. His conclusions resulted in the atomic theory, which helped to explain that atoms in chemical reactions separate, combine or rearrange, but are not created, destroyed, or divided.
