Millikan found the charge of an electron by his famous oil drop experiment.
J J Thomson determined the specific charge of the electron. That means the ratio of the charge of an electron to its mass.
With these two values one can find the mass of electron by dividing the charge value by its specific charge.
What else can I help you with?
What was the scientist name who discovered the electrons charge?
The scientist who discovered the charge of electrons was J.J. Thomson. He determined the charge-to-mass ratio of electrons through his experiments with cathode rays in the late 19th century.
Which scientist performed the cathode ray experiment leading to the discovery of electrons?
Dalton performed the cathode ray experiment.
What subatomic particle has a very small mass and a negative charge?
Electrons have a negative charge. When an element had more electrons than protons, it tends to have a negative charge.
Which of the following statements about subatomic particles is TRUE?
The particles are closely packed together.
Do protons have positive charge neutrons have negative charge and electrons have no charge?
No, protons have positive charge, electrons have negative charge and neutrons have no charge
What was the scientist name who discovered the electrons charge?
The scientist who discovered the charge of electrons was J.J. Thomson. He determined the charge-to-mass ratio of electrons through his experiments with cathode rays in the late 19th century.
In the electron charge to mass experiment if the electron is replaced by a proton or neutron would the charge to mass ratio value still be the same why or why not?
Compared to the (charge/mass) ratio of the electron:-- The (charge/mass) ratio of the proton is much smaller; although the proton charge is equal to the electron charge, the proton mass is much larger, by a factor of more than 1,800.-- The (charge/mass) ratio of the neutron is zero, because the neutron charge is zero.
Who determined the mass-to-charge of an electron?
J.J. Thompson discovered that cathode rays were made up of electrons, and determined the mass-to-charge ratio of the electrons. He found that the mass-to-charge ratio of the cathode rays was much smaller than that of hydrogen, and concluded that constituent particles (electrons) must be the building blocks of atoms. He modeled the neutral atom as a sphere of negatively charged electrons distributed amongst positively charged protons. This is known as the "plum pudding" model or the Thompson model of the electron.Ernest Rutherford proved that the Thompson model was incorrect when he discovered that gold atoms consist of an outside layer of electrons, with a center nucleus densely packed with protons.
Who discovered that an electron has a mass that is very small compared to the size of the atom?
J.J. Thomson discovered that the electron has a very small mass compared to the size of the atom through his experiments with cathode rays in the late 19th century. His work led to the development of the plum pudding model of the atom.
What is charge to mass ratio of neutron?
The neutron has no charge, therefore the charge to mass ratio for the neutron is zero.
How you can derive mass to charge ratio equation?
It is a simple ratio charge/mass or e/m .
Which atom has the highest charge to mass ratio?
The electron has the highest charge to mass ratio. This is because it has a tiny mass compared to its charge, making its ratio very high.
Why is the charge to mass ratio of proton not constant?
The charge and mass ratio of proton is constant, the positive particles found during discharge tube experiment are nuclei of atoms which have different charge and mass ratio.
Charge to mass ratio of electron?
The charge to mass ratio of an electron is approximately -1.76 x 10^11 coulombs per kilogram. This means that electrons have a very small mass compared to their charge. This value was first measured by J.J. Thomson in his experiments with cathode rays.
What is an alternative method to measure the charge to mass ratio of an electron?
Modern Mass Spectrometry is the alternative method to measure the charge to mass ratio of an electron.
Which scientist performed the cathode ray experiment leading to the discovery of electrons?
Dalton performed the cathode ray experiment.
Who calculated the mass of an electron?
J.J. Thompson discovered that cathode rays were made up of electrons, and determined the mass-to-charge ratio of the electrons.
