This became the classic means of measuring the charge-to-mass ratio of the electron. Later in 1899 he measured the charge of the electron to be of 6.8 × 10 −10 esu. [33] Thomson believed that the corpuscles emerged from the atoms of the trace gas inside his cathode-ray tubes. He thus concluded that atoms were divisible, and that the ...
Tax rates were 3% on income exceeding $600 and less than $10,000, and 5% on income exceeding $10,000. [8] This tax was repealed and replaced by another income tax in the Revenue Act of 1862.

George Johnstone Stoney (15 February 1826 – 5 July 1911) was an Irish physicist known for introducing the term electron as the "fundamental unit quantity of electricity". [1] He initially named it "electrolion" in 1881, [2] and later named it “electron” in 1891. [3] [4] [5] He published around 75 scientific papers during his lifetime.
