Web27 de set. de 2024 · Thomson’s Atomic Model In 1897, Thomson claimed that the basic body of an atom is spherical in shape that contains electrons (tiny particles within the atom that create a negative charge) and a positively charged “jelly” around the electrons that neutralize the charge of the electrons. WebThomson finally proved atoms were made up of smaller components, something scientists had been puzzled by for a long time. Thomson called the particle “corpuscles”, not an electron. The name electron was suggested by George Francis Fitzgerald. Why was the discovery of the electron important?
