Variation Between Elements Conversely, Dalton proposed that atoms of different elements possess different masses and properties. The Third Point: Compounds Form from Combined Atoms Dalton’s theory further states that compounds are formed when atoms of different elements combine in fixed, simple whole-number ratios.
Understanding the Core Principles of Dalton Atomic Theory
He asserted that during a chemical reaction, atoms are separated, combined, or rearranged, but they themselves are not altered or destroyed. For instance, every water molecule is composed of the same types and numbers of atoms, ensuring consistent composition and behavior across all samples of pure water.
John Dalton’s atomic theory, first presented in 1803, fundamentally reshaped how scientists understand matter. This phenomenon is a direct consequence of atoms combining in different numerical ratios, such as the difference between water (H₂O) and hydrogen peroxide (H₂O₂).

Dalton used this to explain the uniformity of chemical compounds. This conservation of atoms during reactions provides a logical mechanism for mass conservation, aligning with the foundational principles of physics.
