In 1808, John Dalton proposed a series of statements regarding the atom that became known as Dalton's postulates or Dalton's ato
mic theory. Since Dalton's original proposal, some of the statements have been updated or changed due to new discoveries. Which of the statements was not a part of Dalton's original atomic theory? Matter is comprised of small particles called atoms. All four statements are part of Dalton's original atomic theory. Different elements have atoms of different masses and properties. Atoms of the same element have the same size, mass, and structure. Atoms cannot be created or destroyed in a chemical reaction.
The statement above is true. He conducted the oil-drop experiment which lead him to determine the charge of the electron. He suspended charged droplets into an oil which is in between two electrodes and balancing the upward force with the downward forces.
Ranking of the atom from highest to lowest is as follows: Highest Arrow = from outer edge to center 2nd Highest Arrow = second closest ring to the outer edge to center 3rd Highest Arrow = middle circle to center Lowest Arrow = outer edge to middle circle
