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 has a mass of 0 amu and a charge of -1?
The electron has a charge of -1; but the electron has a mass.
Define negative charge without using mass of electron?
Mass and charge are not connected. Negative charge is the charge carried by an electron.
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 the charge and mass of a electron?
The charge of an electron is -1. Specifically, it is about -1.602 x 10-19 coulombs. The mass of an electron is about 9.109 x 10-31 kilograms, or about one 1836th that of a proton.
Is the the mass and charge of electrons compare to that of protons?
The mass of an electron is much smaller than the mass of a proton. An electron has a charge of -1, while a proton has a charge of +1.
Who discovered the amount of charge on an electron?
Voltaire
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.
Elementary particle that carries a negative charge and almost no mass?
A electron is a subatomic particle outside the nucleus carrying a negative charge and very little mass. Other mass is negligible mass or a negative charge.
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 discovered the electrical charge of the electron?
J.j. Thomson
The subatomic particle that J J Thomson discovered has an?
He discovered the electron which has a negative charge of 1.602 x 10-19 coulombs and a mass of 9.1 x 10-31 kg.
