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 mean by specific charge of an electron?
The specific charge of an electron is its charge-to-mass ratio. It quantifies how the charge of an electron compares to its mass and is approximately -1.76 x 10^11 coulombs per kilogram. This property plays a crucial role in understanding the behavior of electrons in electromagnetic fields.
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 has more mass-a proton or electron?
The proton has much more mass than the electron, by a factor of 1836 times, a ratio called "mu". Recent astronomical research suggests mu may have changed by 20 parts per million in the last 12 billion years, but I plan to wait at least a billion years for confirmation!
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.
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.
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.
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.
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.
What has a positive electrical charge and is 2000 times the mass of an electron?
A proton has a positive electrical charge and is approximately 2000 times the mass of an electron.
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.
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.
