The identification of the basic unit of damaging electrical cost, a subatomic particle now identified, didn’t happen with a single, definitive act of discovery attributed to at least one particular person. As an alternative, the understanding of this particle emerged from a sequence of experiments and theoretical developments by a number of scientists. Key experiments involving cathode rays, streams of electrons in vacuum tubes, performed a vital function. These experiments offered proof of particles smaller than atoms carrying damaging fees.

The collective efforts of researchers like Julius Plcker, Johann Wilhelm Hittorf, and William Crookes laid the groundwork. Nevertheless, J.J. Thomson is broadly credited with definitively demonstrating the existence of this subatomic particle by his cathode ray tube experiments in 1897. He not solely confirmed its existence but in addition measured its charge-to-mass ratio, a pivotal step in characterizing its basic properties. This discovery revolutionized the understanding of atomic construction and paved the way in which for the event of recent physics and electronics. The next work of Robert Millikan, in figuring out the elementary electrical cost, offered additional essential information.
