What information Julius plucker contribute to the understanding of the atom?

Julius Plücker contributed to the understanding of the atom through his experiments with cathode rays in the mid-19th century. He demonstrated that these rays could be deflected by electric and magnetic fields, suggesting that they were composed of charged particles. This work laid the groundwork for later discoveries in atomic theory, particularly the identification of electrons as subatomic particles. Plücker's findings helped shift scientific focus towards the study of atomic structure and the behavior of particles within it.
