Study Notes
Science as a Jigsaw Puzzle
- Science is compared to a jigsaw puzzle where individual discoveries contribute to a larger understanding.
- Researchers make specific discoveries that, when compiled, enhance comprehension of processes or structures.
- Experiments by scientists like Crooke, Millikan, and Rutherford provided critical insights into the atomic nucleus.
Models of the Atom
- Early models attempted to depict atomic structure after discoveries of electrons and protons.
- The Thomson model proposed a positive core with electrons mixed throughout, aiming for electrical neutrality.
- Rutherford challenged the Thomson model, showing that the nucleus is a small solid core, allowing alpha particles to pass with minimal interaction.
- Post-Rutherford, the model evolved to depict protons and neutrons at the nucleus center, surrounded by electrons.
Discovery of the Neutron
- The introduction of the neutron completed the atomic model, solidifying the structure of the nucleus.
- Protons and neutrons are densely packed in the nucleus, with electrons in orbit around them.
Strong Nuclear Force
- Despite positive charges of protons potentially causing repulsion, a strong nuclear force is postulated to counteract this.
- The strong nuclear force operates at very short distances, overpowering the repulsive action of like charges.
- This force is crucial for the stability of the nucleus, ensuring that protons and neutrons are held together effectively.
