WebMore Information: In 1897, J. J. Thomson dramatically changed the modern view of the atom with his discovery of the electron. Thomson's work suggested that the atom was not an "indivisible" particle as John Dalton had suggested but a jigsaw puzzle made of smaller pieces. Thomson's notion of the electron came from his work with a nineteenth century … Web24 jun. 2013 · 6. Contributions- Thomson devised the famous plum pudding model of the atom, in which electrons were compared to negative plums embedded in a positively charged pudding. The idea was wrong, and his successor at Cambridge, Ernest Rutherford, was soon to develop the nuclear model of the atom. Thomson investigated positive …
What are the contribution of JJ Thomson in chemistry?
WebAnswer: J.J. Thomson discovered the existence of the electron, a negatively-charged particle that’s 1/2000 the relative size of the proton. Before this, people thought that atoms were the smallest possible size of anything in existence, so this meant that there were even smaller particles that ma...

Thomson assumed that an atom is made up of positively charged spheres in which electrons are embedded. In the year 1898, the concept of the nucleus did not exist. Along with the theories available by them, he proposed that “an atom possesses a spherical shape (approximately of around10-10m) where the ... Web14 nov. 2024 · What is JJ Thomson atomic theory? J.J. Thomson’s experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged “soup.” What 2 … health food stores brunswick ga
