  • Hi I am Lucas and I am going to take you through the history of the ATOM
  • present day
  • SCIENCE
  • 460 BC
  • Hi I am Democritus
  • All matter consists of atoms, which cannot be further subdivided into smaller particles. 
  • 1766
  • Hi I am John Dalton and All matter is comprised of tiny, definite particles called atoms.Atoms are indivisible and indestructible.All atoms of a particular element share identical properties,
  • 1831
  • Hi I am Michael Faraday and Atoms have an electrical component. Electrical forces are responsible for the joining of atoms in compounds.
  • He thought that a point would be reached at which the cheese could not be cut into still smaller pieces. He called these pieces atomos, which means “uncuttable” in Greek.
  • 1897
  • He also believed that all compounds were composed of combinations of these atoms in defined ratios.Dalton also postulated that chemical reactions resulted in the rearrangement of the reacting atoms.
  • 1911
  • Hi I am Ernest Rutherford. the atom is mostly empty space, with nearly all of its mass concentrated in a tiny central nucleus. The nucleus is positively charged and surrounded at a great distance by the negatively charged electrons.
  • his discovery was crucial in allowing electricity to be transformed from a curiosity into a powerful new technology.
  • Faraday’s earliest experimental observations was a crucial precursor to the discovery of the first subatomic particle, the electron.
  • He discovered the electron and then went on to propose a model for the structure of the atom. His work also led to the invention of the mass spectrograph.
  • Hi I am JJ Thomson andAll atoms contain tiny negatively charged subatomic particles or electrons.
  • Although proven wrong Thomson's model was correct at the time, because it explained all that scientists then knew about the atom.
  • He also built the model of the atom that we all know today. He had the negatively charged electrons surround the nucleus of an atom.
