Sir Joseph John Thomson was a British physicist whose research lead to the development of the first subatomic particle that is ELECTRON. He was born on December 18, 1856, in Cheetham Hill, England near Manchester. Joseph’s father was a bookseller who wanted him to become an engineer. In 1894, he started studying cathode rays and discovered better equipment and methods. He stated that all the matter is made up of tiny particles and initially called these particles “corpuscles” which were later named ae electron. In 1906, Joseph studied the positively charged ions and proved the existence of isotopes, and invented the new tool for chemical analysis that is Mass Spectrometer. He was awarded Nobel Prize in physics in 1906 and Adam’s prize for his research in atoms (plum pudding model of the atom). In 1907, he also stated that every hydrogen atom has only one electron.
