The five main people who discovered the structure of an atom are John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, and Erwin Schrödinger. John Dalton introduced the idea of atoms. J.J. Thomson discovered the electron. Ernest Rutherford found the nucleus. Niels Bohr proposed electron orbits, and Erwin Schrödinger developed the quantum mechanical model.

FAQs & Answers

  1. What is the significance of John Dalton in atomic theory? John Dalton is significant for introducing the concept of atoms as the fundamental building blocks of matter, laying the groundwork for modern atomic theory.
  2. How did J.J. Thomson contribute to our understanding of atomic structure? J.J. Thomson contributed by discovering the electron, allowing scientists to understand that atoms are made up of even smaller particles.
  3. What was Ernest Rutherford's major discovery? Ernest Rutherford's major discovery was the nucleus, leading to the realization that an atom has a dense center that contains protons and neutrons.
  4. What role did Niels Bohr play in atomic theory? Niels Bohr played a key role by proposing the Bohr model, which introduced the idea of quantized electron orbits around the nucleus, shaping our understanding of atomic structure.
