Niels Bohr and Ernest Rutherford suggested the modern structure of an atom. While Rutherford proposed the nuclear model with a small, dense nucleus, Bohr refined it, introducing defined orbits for electrons.

FAQs & Answers

  1. What is the Bohr model of the atom? The Bohr model of the atom, proposed by Niels Bohr, suggests that electrons exist in specific orbits around the nucleus and have quantized energy levels.
  2. Who is Ernest Rutherford and what did he contribute to atomic theory? Ernest Rutherford is known for his pioneering research in nuclear physics, particularly the Rutherford model of the atom, which introduced the idea of a small, dense nucleus at the center of the atom.
  3. How did Rutherford's and Bohr's ideas about the atom differ? Rutherford introduced the concept of a nucleus within the atom, while Bohr built upon this model by proposing that electrons travel in defined circular orbits, quantizing their energy levels.
  4. What is the significance of the structure of an atom in science? Understanding the structure of an atom is fundamental for various scientific fields, as it lays the groundwork for chemistry, physics, and understanding the behavior of matter.
