- - - - His contribution to chemistry, especially in Atomic Science, he was thought which were a mechanical “corpuscular hypothesis. This a brand of atomism which claimed that everything was composed of minute but not indivisible particles, of a single universal matter and that these particles were only differential by their shape and motion. His most famous contribution was the definition of an element which the element could be made from 2 or more substance which is not an element.
      - It is Boyle's Law for which he remains most famous. This states that if the volume of a gas is decreased, the pressure increases proportionally. Understanding that his results could be explained if all gases were made of tiny particles, Boyle tried to construct a universal 'corpuscular theory' of chemistry.
  - - - Dalton’s atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass.
      - Dalton’s most influential work in chemistry was his atomic theory. The theoretical foundation of Dalton’s atom theory was mainly based on the law of conservation of mass and the law of definite proportional), both of which had already been established, and the law of He based his theory of partial pressures on the idea that only like atoms in a mixture of gases repel one another, whereas unlike atoms appear to react indifferently toward each other. multiple proportions) which was developed by Dalton himself.
- - - - All atomic nuclei except those of ordinary hydrogen contain a subatomic particle with about the same mass as a proton but no electric charge.
  - - - Protons are the positively charged particles which make it up a hydrogen atom's nucleus.
    - - The central and most important part of an object, movement, or group, forming the basis for its activity and growth.
- - - - It was proposed by J.J Thomson in 1904. This model was conceived after Thomson's discovery of the electron as a discrete particle, but before it was understood that the atom had a central nuclues.
  - - - It was proposed by the Nobel Prize-winning chemist Ernest Rutherford in 1911 and is sometimes called the Rutherford Model.
