Early in the 20th century, a leading model of the structure of the atom was that of English physicist J. J. Thomson (the discoverer of the electron). In Thomson’s model, an atom consisted of a sphere of positively charged material in which were embedded negatively charged electrons, like chocolate chips in a ball of cookie dough. J.J. Thomson () Sir Joseph John Thomson was born in Cheetham Hill, a suburb of Manchester on Decem He enrolled at Owens College, Manchester, in , and in entered Trinity College, Cambridge as a minor scholar.

Thomson Discoverer of the Electron 1 J. J. Thomson Discoverer of the Electron () 2 In J.J. Thomsons experiments he was able to bend the cathode ray (which travels in a straight line) by applying either an electric field or a magnetic field. By finding the displacement of the ray he was able to calculate electric charge.

Daltons theory of the atom was very useful for quite a while, but his theory of the atom was that the atom was a solid indivisible mass. But the discovery of subatomic particles shattered every theory scientists has about indivisible atoms. The discoverer of the electron was J.J. Thomson. Joseph John Thomson (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. He is known for the Thomson atomic theory. Many scientists studied the electric discharge of a cathode ray tube. The Discovery Of The Electron The electron was discovered in by n in the form of cathode rays, and was the first elementary particle to be identified.

The electron is the lightest known particle which possesses an electric charge. Its rest mass is Me x 10 g, about 1/ of the mass of the proton or neutron. The charge of the electron is -e = J.J. Thomson decided to find out for sure.

Thomson was a physics professor at Cambridge University in the UK. He placed cathode tubes in electric and magnetic fields.

the electron turned out. This interesting book locates Thomson's ideas in their historical and philosophical context, revealing a consistent world view that runs through all of his work.

In fact this world view could be regarded as the key to why we remember Thomson as the discoverer of the electron rather than any of the many others who were carrying out similar Author: S F Adams.

Thomson's life and experiments leading to the discovery. The Foreword is by Thomson's grandson.4/5(1). Sir Joseph John "J. J." Thomson, OM, FRS (18 December 30 August ) was a British physicist. In Thomson showed that cathode rays were composed of a previously unknown negatively charged particle, and thus he is credited with the discovery and identification of the electron; and, in a broader sense, with the discovery of the first subatomic particle.4/5(1).

Thomson then measured the deflection produced by the electric field alone. This, combined with the values of E, v and d, gave the value of the ratio of the charge e to the mass m of the particles. Thomson's claim to be the discoverer of the electron rests on two key observations. At Cambridge, the young Rutherford worked in the Cavendish lab with J.J.
