Joseph John Thomson, and others, while at the Cavendish Laboratory of the University of Cambridge, made a rough estimate of the electronic charge. Robert Andrew Millikan, between 1906 and 1914, enhanced the work of Thompson, et al, and determined the electric charge to much higher precision. Along with the mass-to-charge ratio determined by electolysis, this gave the best values for atomic masses. These results were the most accurate basis for the atomic scale. The largest change was measured in the 1930s. Today, the best value of the electronic charge is only 1 percent higher than that measured by Milllikan in 1913.

What is Thomson's full name?
Mick Thomson from Slipknot's full name is Mickael Gordon Thomson
What did Thomson use in his experiments?
J.J. Thomson studied the deflection of cathode rays in electric and magnetic fields.
Why was it important for Thomson to repeat his experiment?
Thomson did the experiment various times to observe if the particles behave the same way. How they did he determined they were the same kind later called electrons.
Were there experiences in jj thomson life that led to his interest in science and the study of the atom?
mabby
When did Thomson conduct the cathode-ray tube experiment?
At the end of the 1800's
Robert millikan's major contributions to the atomic theory?
Millikan: He discovered that the weight of an electron is 1840 times smaller than a hydrogen atom (atomis mass of 1) Thomson: Thomson was the first person to suggest the theory of the atom containing positive and negative particles, and demonstrated the latter which called electrons
What experimental evidence did Thomson have atoms of all elements contain electrons?
The deflection of cathodic rays was the source of inspiration for Thomson.
What experimental evidence did Thomson have for the atoms of all elements contain electrons?
The deflection of cathodic rays was the source of inspiration for Thomson.
Who conducted experiments to determine the quantity of charge carried by electron?
With his oil drop experiment, R.A. Milikan attempted to learn about the quantity of change carried by an electron. His discoveries are instrumental to particle and atomic theories.
He conducted the cathode-ray tube experiment?
J.J Thomson conducted the cathode-ray tube experiment in 1911.
When did JJ Thomson do stuff about the atom?
Thomson did much of his most important work in the late 1800's. His famous cathode ray experiments where conducted in 1897.
Who discovered conducted experiments in combining elements?
John Dalton conducted experiments combining elements with atoms.
Who performed an experiment with cathode ray tubes?
J. J. ThomsonJ. J. Thomson did the cathode ray experiment where he discovered the existence of electrons.
Why did Joseph John Thomson win The Nobel Prize in Physics in 1906?
The Nobel Prize in Physics 1906 was awarded to J.J. Thomson in recognition of the great merits of his theoretical and experimental investigations on the conduction of electricity by gases.
Why did George Paget Thomson win The Nobel Prize in Physics in 1937?
The Nobel Prize in Physics 1937 was awarded jointly to Clinton Joseph Davisson and George Paget Thomson for their experimental discovery of the diffraction of electrons by crystals
What observation did Thomson make to suggest that an electron has a negative electric charge?
The deflection of cathodic rays was the source of inspiration for Thomson.
Which scientist did experiments involing a form of cathode ray tube?
J.J. Thomson used cathode ray tubes to prove the existence of electrons.
