JOHN DALTON’S ATOMIC THEORY OR MODEL. According to Dalton’s atomic theory, atoms are indivisible particles. 4), is a fundamental concept that states that all elements are composed of atoms. John Dalton (1766 – 1844 AD) was a science teacher who also kept detailed records of the weather. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. The modern atomic theory indicated the defects of Dalton’s atomic theory. These are called, Atoms are not always combined in small numbers. The development of this first atomic theory was influenced by facts like the dissolution of different gases in water in different proportions, the composition of tin oxide with  88% Tin while the rest being oxygen, etc. Figure 02: The structure of Helium atom according to the modern atomic theory.

N.p., n.d. It stated that all matter was made up of small, indivisible particles known as ‘atoms’. The key difference between Dalton’s Atomic Theory and Modern Atomic Theory is that the structure and properties of atom according to Dalton’s theory are different from the structure and properties proposed by the modern atomic theory. Ans: John Dalton based his theory on two laws. (i) Atoms are divisible into sub-atomic particles like protons, neutrons and electrons. makaylajordan17. Please download PDF version here Difference Between Dalton’s Atomic Theory and Modern Atomic Theory. Then Dalton proposed the following postulates. Dalton would propose that all the atoms of each element weighed the same, that the particular weight could vary for separate elements and that atoms of these elements combined with each other in simple fixed proportions to make larger atoms which would become known as molecules. Modern atomic theory is the theory that explains the fully detailed structure of an atom.
