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.

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.
The charge and mass number of a proton are?
No, there are the same number of protons and electrons in an atom, but I don't think that they have the same mass. You're right, an electron is 1,836 times lighter than a proton.
Is electrostatic force charge independent of mass?
No, greater mass equates to greater surface area and therefore greater electron-charge storage potential.
What is an electron composed of?
An electron is an elementary particle; it does not have any simpler particles inside it. It is composed of mass, electric charge, and spin.
Relative mass of electron?
1/1840 the mass if a hydrogen atom.
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.
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 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.
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.
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.
When were mass and charge of the electron was discovered?
in 1897
What is the subatomic particle with a mass number of zero and a charge of -1?
In the atom a proton has the charge +1 and the electron the charge -1.
A particle that has mass and a positive electrical charge?
There are three atomic particles with mass, the proton, neutron and electron. Of these three, the proton is the particle with a positive charge.
Compare and contrast protons and neutrons?
Proton: 1,007 276 466 77(10) atomic mass units (u); positive electrical charge, component of the atomic nucleus Neutron: 1,008 664 915 6 (6) atomic mass units (u); neutral, component of the atomic nucleus Electron: 5,485 799 094 3(23).10-4 atomic mass units (u); negative electrical charge, components of the atom
What did Robert milikan discover?
Millikan's oil-drop experiment demonstrated that charge is quantized, and that the quantum of charge ... the 'elementary' charge ... is 1.6 x 10-19 Coulomb.
How is a positron different from an electron?
A positron is an electron's antiparticle. It has the same mass as an electron, but an opposite electrical charge.
