The Timeline

1803 — 2020s

  1. 1803

    John Dalton's Atomic Theory

    John Dalton proposed his atomic theory, which suggested that matter is composed of indivisible atoms. He introduced the concept of atomic weights and laid the groundwork for future Aportaciones modelos atómicos by establishing that each element consists of unique atoms with specific weights.
  2. 1897

    J.J. Thomson and the Electron

    J.J. Thomson discovered the electron through his cathode ray experiments. His findings led to the development of the "plum pudding" model of the atom, where electrons were embedded in a positively charged "soup." This was a significant Aportaciones modelos atómicos that challenged previous notions of atomic structure.
  3. 1911

    Ernest Rutherford's Nuclear Model

    Ernest Rutherford conducted his gold foil experiment, which revealed that atoms have a small, dense nucleus surrounded by orbiting electrons. This nuclear model was a crucial Aportaciones modelos atómicos that replaced Thomson's model and provided a clearer understanding of atomic structure.
  4. 1913
