From Plums to Protons: JJ Thomson's Astonishing Journey to the Atomic Theory

    The US is at the forefront of atomic research, with institutions like the Department of Energy and the National Science Foundation investing heavily in projects related to atomic theory. Additionally, the discovery of new subatomic particles and the development of advanced technologies have sparked renewed interest in the fundamental building blocks of matter.

    • Neutrons: particles with no charge found in the nucleus of an atom.
    • Fact: Protons and neutrons are distinct particles with different properties.
    • Atomic theory is based on the idea that matter is composed of tiny particles called atoms, which in turn are made up of even smaller particles called protons, neutrons, and electrons. Atoms are the basic units of matter, and understanding how they interact with each other is crucial to developing new technologies and advancing scientific knowledge. The atomic model has undergone significant changes over the years, from Thomson's plum pudding model to the modern quantum mechanical model.

    • Fact: Atoms are made up of even smaller particles called protons, neutrons, and electrons.
    • Thomson's plum pudding model was an early attempt to describe the structure of atoms. According to this model, atoms consisted of a positively charged sphere with negatively charged electrons embedded within it, similar to plums in a pudding. This model was later disproven by Ernest Rutherford's gold foil experiment, but it remains an important milestone in the development of atomic theory.
