    The observations that John found -
    The Observation - the ancient concept of atoms into a scientific theory that has become a foundation of modern chemistry. These observations led Dalton to study gases, and from the results of his experiments he was able to formulate his atomic theory.

    Explanation of observation -
    Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and properties. 1-of his theory states that all matter is made of atoms, which are indivisible.2-of the theory says all atoms of a given element are identical in mass and properties.3-says compounds are combinations of two or more different types of atoms.The fourth part of the theory states that a chemical reaction is a rearrangement of atoms.

    The atomic theory or model that was produced.
    He is best known for proposing the modern atomic theory and for his research into colour blindness. Democritus first suggested the existence of the atom but it took almost two millennia before the atom was placed on a solid foothold as a fundamental chemical object by John Dalton

    The experiment that they carried out to explore the atomic structure
    1. Matter is made up of atoms that are indivisible and indestructible.
    2. All atoms of an element are identical.
    3. Atoms of different elements have different weights and different chemical properties.
    4. Atoms of different elements combine in simple whole numbers to form compounds.
    5. Atoms cannot be created or destroyed. When a compound decomposes, the atoms are recovered unchanged.
