Why was Thompson's discovery of the electron so important?

A. It explained the concept of isotopes in an element.
B. It disproved the existence of a nucleus.
C. It meant there was something tinier than the atom itself.
D. It suggested all atoms were a uniform mixture.

J.J. Thomson's discovery of the electron was crucial as it demonstrated that atoms have substructures, revealing the existence of smaller bodies than atoms - electrons.

Thomson's work using cathode rays and his calculation of the charge-to-mass ratio of electrons led to the understanding of atoms having a nucleus with surrounding electrons, debunking the idea of a uniform mixture.

The discovery of the electron fundamentally changed the understanding of atomic structure and laid the groundwork for future advancements in particle physics.
