Who proposed electrons?

The concept of electrons, the subatomic particles that play a crucial role in the structure of atoms, was proposed by British physicist J.J. Thomson in the late 19th century. Thomson is best known for his discovery of the electron through his experiments with cathode rays. His groundbreaking work revolutionized the field of physics and laid the foundation for our current understanding of the atomic structure.

Thomson's experiments with cathode rays led him to conclude that these rays were composed of negatively charged particles, which he called electrons. This discovery challenged the prevailing belief at the time that atoms were indivisible and led to the development of the plum pudding model of the atom, where electrons were embedded in a positively charged sphere.

Thomson's proposal of electrons marked a significant shift in the scientific community's understanding of the nature of matter. It paved the way for further research into the structure of atoms and laid the groundwork for the development of quantum mechanics. Thomson's work laid the foundation for future advancements in the field of physics and solidified his place as one of the most influential scientists of his time.

In conclusion, J.J. Thomson is credited with proposing the existence of electrons through his experiments with cathode rays. His groundbreaking work revolutionized the field of physics and laid the foundation for our current understanding of the atomic structure. Thomson's contributions to science continue to be celebrated and studied to this day, highlighting the impact of his discoveries on the world of physics.
