Essay / Research Paper Abstract
3 pages in length. An historic marvel occurred at the turn of the nineteenth century that would once again bring man a better understanding of the world around him. J.J. Thomson's discovery of the electron originated when he found that cathode rays were negatively charged particles, a breakthrough he termed corpuscles, noting how their size was approximately one thousand times smaller than hydrogen atoms. The British physicist further claimed that atomic existence was integrally based upon the existence of these corpuscles, a fact he boldly addressed in 1897. Bibliography lists 4 sources.

found that cathode rays were negatively charged particles, a breakthrough he termed corpuscles, noting how their size was approximately one thousand times smaller than hydrogen atoms. The British physicist
further claimed that atomic existence was integrally based upon the existence of these corpuscles, a fact he boldly addressed in 1897: "...We have in the cathode rays matter in
a new state, a state in which the subdivision of matter is carried very much farther than in the ordinary gaseous state: a state in which all matter - that
is, matter derived from different sources such as hydrogen, oxygen, etc. - is of one and the same kind; this matter being the substance from which the chemical elements are
built up." (Thomson, 1897, p. 295). The reality of such a claim was quite astonishing to the scientific community, inasmuch it was difficult to perceive of anything being smaller
than an atom itself. However, Thomson was indeed correct in his assertion that the atom was able to be divided into smaller particles, the collection of which ultimately comprises
what is known as "the most fundamental unit of matter" (American Institute of Physics, 2003). Highly respected physicists continued to cast a skeptical eye upon Thomsons claim, even to
the point of questioning whether there was any validity to his discovery whatsoever. While it did take some time for Thomson to be taken seriously, the scientific community did
finally realize the truth of his disclosure some two years later. "At first there were very few who believed in the existence of these bodies smaller than atoms. (Thomson,
1936, p. 341). By 1899, Irish physicist George Francis Fitzgerald concurred to a point with Thomsons finding, opting to alter the name from corpuscles to free electrons to explain the
