J.J.Thompson determined the electron charge to mass ratio. His results, however, were off by almost a factor of two, although they were consistent, leading us to believe there was some systematic error in his measurements.

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.


Who discovered the charge to mass ratio for the electrons?

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 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.


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.


What particles account for the charge of the mass?

Protons and electrons are particles that account for the charge of the mass. Protons have a positive charge, while electrons have a negative charge. The net charge of an object is determined by the balance of these two particles.


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.


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.


How does the mass to charge ratio of cathode rays compare to that of anode rays?

it varies because charge to mass ratio of positive rays depends upon gases used in the discharge tube.its varies from gas to gas.


How did Thomson determine charge to mass ratio of electron?

J.J. Thomson determined the charge-to-mass ratio of the electron (e/m) using a cathode ray tube experiment. He measured the deflection of cathode rays (which are streams of electrons) in electric and magnetic fields. By analyzing the curvature of the electron's path and applying the equations of motion, he could calculate the ratio of the charge of the electron to its mass. This groundbreaking work led to the identification of the electron as a fundamental particle.


Charge-mass ratio of a proton?

The charge-mass ratio of a proton is approximately 9.58 x 10^7 coulombs per kilogram (C/kg). This value is a fundamental property that describes the ratio of the charge of a proton to its mass. It is commonly used in particle physics experiments and calculations.
