Thomson discovery atom
WebMar 15, 2024 · So, the answer to the question is: The discovery of J.J Thomson showed that an atom is divisible. Later on , the divisibility of an atom is also proved by the discovery of the proton by Ernest Rutherford. He is also known as the father of the proton. Unlike electrons, protons bear a positive charge. The discovery of neutrons as a subatomic ... WebJ.J. Thomson was an English physicist who discovered the electron in 1897. Prior to Thomson’s discovery, it was thought that atoms were indivisible units of matter. However, Thomson’s experiments showed that atoms are actually made up of smaller particles. He concluded that atoms must have a small, central nucleus with electrons orbiting ...

WebBohr soon went to visit Ernest Rutherford (a former student of Thomson's) in another part of England, where Rutherford had made a brand-new discovery about the atom. In 1912 Bohr joined Rutherford. WebA series of experiments with cathode rays he carried out near the end of the 19th century led to his discovery of the electron, a negatively charged atomic particle with very little mass. Thomson received the Nobel Prize in Physics in 1906 for his work exploring the electrical conductivity of various gases. The son of a bookseller, Thomson was ...
