  1. 2. 1913 developed the Bohr model of the atom
  2. 4. Late 19th Century, Photons are packets of light
  3. 5. 1926 provided a mathematical description of the behavior of electrons in atoms
  4. 8. Late 18th century a French chemist, made significant contributions to chemistry. His work on the conservation of mass laid the foundation for understanding chemical reactions and influenced the development of atomic theory.
  5. 9. Late 19th to early 20th century, She discovered the elements polonium and radium
  6. 10. Mid-20th century made significant contributions to the discovery of transuranium elements
  7. 12. 1960s proposed the quark model introducing the idea that protons, neutrons, and other hadrons are composed of smaller subatomic particles
  8. 15. 1897 discovered electrons through cathode ray experiments
  9. 16. 19th century a Scottish physicist who contributed to the understanding of electromagnetism. His equations,
  10. 17. 19th century Russian chemist who organized the known elements into the periodic table based on their properties and atomic masses
  11. 19. 1924 proposed the wave-particle duality of matter, suggesting that particles like electrons exhibit both wave and particle properties
  12. 20. 20th century His Feynman diagrams are widely used to represent particle interactions.
Down
  1. 1. 460–370 BCE an ancient Greek philosopher, introduced the concept of atomos
  2. 3. Mid-20th century won the Nobel Prize in Chemistry for his research on the nature of the chemical bond
  3. 6. 1803 proposed that elements are composed of indivisible atoms and that chemical reactions involve the rearrangement of these atoms in fixed ratios
  4. 7. 1925 Formulated matrix mechanics and uncertainty principle
  5. 11. 1909 conducted the famous gold foil experiment
  6. 13. 384–322 BCE rejected the idea of indivisible particles. Instead, he proposed a continuous matter theory, which dominated scientific thought for centuries.
  7. 14. Early 20th century conducted the oil-drop experiment which helped determine the charge of the electron
  8. 18. Early 20th century explained the photoelectric effect which supported the quantum theory of light
