Charge on an electron was first determined by
WebGoldstein's experiments showed that matter contained positively charged particles, leading to the discovery of protons. Thomson's experiment led to the determination of the mass-to-charge ratio for an electron. Suppose that each of the following changes is made.Give the symbol for the element whose electron configuration matches the result. Irish physicist George Johnstone Stoney named this charge 'electron' in 1891, and J. J. Thomson and his team of British physicists identified it as a particle in 1897 during the cathode-ray tube experiment. Electrons can also participate in nuclear reactions, such as nucleosynthesis in stars, where they are known as beta … See more The electron ( e or β ) is a subatomic particle with a negative one elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because … See more Classification In the Standard Model of particle physics, electrons belong to the group of subatomic particles called See more Remote observation of electrons requires detection of their radiated energy.
