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 would the charge be if an atom gains an electron and why?
Every electron has a charge of minus one. If a neutral atom acquires an additional electron, then it also acquires the charge of that electron, and will have a net charge of minus one.
Why hole has positive charge?
A hole is a place where an electron is missing. Since the electron has a negative charge, the lack of an electron produces a net positive charge.
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.
What is the charge on an electron in SI units?
A neutron has no charge (neutron-neutral). It is simply there for weight.
How do you work out specific charge?
To work out the specific charge of a given element, you will take the positive electron charge and multiply it by the negative electron charge. This can be calculated by the formula q=ne

What is The ratio of the specific charge of an electron to that of a positron is?
1:1
What emits electrons in specific charge of electron experiment?
hot filament
How do you find out the no of electrons in a specific charge?
Number of electrons = the number of protons. Electron and proton number of a specific charge is always same. :-) Hope this helped! Cheers, Brandon.
Why alpha particle has lowest specific charge than electron and protonGive reason?
The question is incorrect. (Either that, or I don't know what "specific charge" means.) The alpha particle has a charge of +2, while the proton is +1 and the electron is -1.If you are talking about charge to mass ratio, however, it is true that the alpha particle has a mass of about 4 amu, while the proton is 1 amu, and the electron is 1/1836 amu. This makes the charge to mass ratio of the alpha particle to only be about 0.25, while the proton is 1.0 and the electron is -1836.
What part of the atom has a negative charge is the?
Electron Carries A Negative Charge.
How is the specific charge of an electron affected when its speed increases?
Its charge is always 1.6X10-19 However when it's speed increases, it has more energy
Does an electron or proton have a larger charge?
No. The electron and proton have the same amount of charge. Its just that the electron's charge is negative and the proton's charge is positive.
Is the charge of a electron always equal to the charge on a neutron?
The charge on an electron is never equal to the charge on a neutron. An electron carries one negative charge and a neutron has no net charge.
Does a Netron have a negative charge?
I assume that you mean 'neutron.'NO!, a Neutron does not have any charge ... it's Neutral.It's the Electron that has the negative charge and, the Proton has a positive charge.
