Summary
Owen Willans Richardson's "The Electron Theory of Matter" asserts that the fundamental constituents of matter are electrons, and their behavior explains electrical phenomena, chemical bonding, and the physical properties of substances. The book argues that the electron is a corpuscular entity carrying a negative electric charge and possessing a definite mass, and that these properties are invariant across different elements and conditions. Readers gain an understanding of how the concept of the electron unified previously disparate observations in physics and chemistry, establishing a foundation for modern atomic theory and the understanding of electricity.
The work systematically details the experimental evidence for the electron, including its discovery by J.J. Thomson. Richardson explains how electron emission from heated surfaces (thermionic emission) and the interaction of electrons with electric and magnetic fields reveal their characteristics. The theory's application to explain phenomena such as electrolysis, the photoelectric effect, and the nature of X-rays is a key focus, demonstrating the electron's role in diverse physical and chemical processes.

Key concepts
- Electron — A fundamental particle carrying a negative electric charge and possessing mass, proposed as the key constituent of matter.
- Thermionic Emission — The emission of electrons from a heated conductor, a phenomenon explained by the electron theory.
- Corpuscularian Theory — The idea that matter is composed of discrete particles, in this context specifically electrons.
- Charge-to-Mass Ratio (e/m) — The experimental determination of the ratio of an electron's electric charge to its mass, a crucial piece of evidence for its existence.
