Thomson atomic model, earliest theoretical description of the inner structure of atoms, proposed about 1900 by William Thomson (Lord Kelvin) and strongly supported by Sir Joseph John Thomson, who had discovered (1897) the electron, a negatively charged part of every atom.

2020年2月2日 · J.J. Thomson is credited with the discovery of the electron, the negatively charged particle in the atom. He is known for the Thomson atomic theory. Many scientists studied the electric discharge of a cathode ray tube. It was Thomson's interpretation that was important.

2025年1月23日 · J.J. Thomson, English physicist who helped revolutionize the knowledge of atomic structure by his discovery of the electron (1897). He received the Nobel Prize for Physics in 1906 and was knighted two years later.

Thomson model Introduction. Thomson atomic model was proposed by William Thomson in the year 1900. This model explained the description of an inner structure of the atom theoretically. It was strongly supported by Sir Joseph Thomson, who had discovered the electron earlier.

Following his discovery of the electron in 1897, British Physicist J.J. Thomson proposed a model of the atom in 1904 after doing a series of cathode tube experiments. According to his hypothesis, an atom consists of positive and negative charges present in equal amounts so that it is electrically neutral.

2023年12月19日 · Thomson’s Atomic Model was proposed by J.J. Thomson in 1904, following his discovery of the electron in 1897 after his famous cathode ray experiment. The model is also known as the Plum Pudding Model.

2021年5月30日 · In 1904, Joseph John Thomson proposed an evolution of Dalton's atomic model, giving rise to the famous Thomson model, a revolutionary theory that attempted to explain two fundamental properties of atoms at the time.

His nonmathematical atomic theory—unlike early quantum theory—could also be used to account for chemical bonding and molecular structure (see Gilbert Newton Lewis and Irving Langmuir). In 1913 Thomson published an influential monograph urging chemists to use the mass spectrograph in their analyses.
