Thomson discover the electron in 1897? Well, according to Thomson: “the discovery of the electron began with an attempt to explain the discrepancy between the behavior of cathode rays under magnetic and electric forces. In fact, a full eight of his research assistants and his son eventually earned Nobel Prizes, but, of course, like Thomson’s own Nobel Prize, that was in the future. He ended up having an unerring ability to pinpoint interesting phenomena for himself and for others. ” Suddenly, he had incredible resources, stability, and the ability to research whatever he wished. He mostly applied as a lark and was as surprised as anyone to actually get the position! “I felt like a fisherman who…had casually cast a line in an unlikely spot and hooked a fish much too heavy for him to land. In 1884, at the tender age of 28, Thomson applied to be the head of the Cavendish Research Institute. Instead, he relied on scholarships at universities – ironically leading him too much greater fame in academia. ” While in school, his father died, and his family didn’t have enough money for the apprenticeship. Thompson later recalled that “the authorities at Owens College thought my admission was such a scandal – I expect they feared that students would soon be coming in perambulators – that they passed regulations raising the minimum age for admission so that such a catastrophe should not happen again. When he was 14 years old, Thomson planned to get an apprenticeship as a locomotive engineer but it had a long waiting list, so, he applied to and was accepted at that very young age to Owen’s college. Want to know not only how but why electrons were discovered? Let’s go!Ī short history of Thomson: Joseph John Thomson, J J on papers, to friends, and even to his own son, was born in Lancashire, England to a middle-class bookseller. However, most videos miss what JJ Thomson himself said was the motivating factor: a debate about how cathode rays move. In this problem we have given that JJ Thomson cathode ray tube experiment demonstrated that cathode rays are streams of negatively charged ions all the mass of an atom is essential in the nuclear the electron to mass ratio of electron is much greater than electron to mass ratio of proton electron to mass ratio of cathode rays particles changes are different gases placed in the discharge tube to in Thomson experiment there was a discharge due in which in which in which when he died when idiot cathode ray tube experiment to basically cathode rays cathode rays are cathode rays are basically negatively negatively charged rays are stream of cathode rays are streams of negativelyĬharged ions ok negatively charged Ion charged ion and the electron to mass ratio of the electron to mass ratio of electron of electron is basically 1837 time electron to mass ratio charge to mass ratio charge to mass ratio of proton ok so we can say that charge to mass ratio of electron is much higher than the charge to mass ratio of proton because charge of an electron and proton is given as 1.6 into 10 to the power minus 19 coulomb plus minus and mass of electron is given as 9.1 into 10 to the power minus 31 kg and mass of proton is given as 1.JJ Thomson discovered the electron in 1897 and there are tons of videos about it.
