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.
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!
What is unit of magnetic charge?
Rate of change of electric charge produces magnetic charge. Unit of electric charge is coulomb C, unit of magnetic charge would be Ampere-meter.
An electron and a proton are situated in a uniform electric field.what is the ratio of their acceleration?
The charges on proton and electron are equal in magnitude. hence, the electric force F(=eE) on them will be equal in magnitude.Acceleration of electron,ae=F/me=eE/meAcceleration of proton,ap=F/mp=eE/1836meTherefore,ae/ap=1836
The stability of a nuclide depends on the?
The stability of a nuclide depends on:the specific neutron/proton ratio that corresponds to a stable nucleus, and orthe number of protons not to exceed the stability limit (exceeding 83).Referring to question below for more information.
What is specific charge ratio of proton and alfa particle?
The charge ratio of a proton to an alpha particle is 1:2. An alpha particle is merely a helium nucleus, composed of exactly two protons and usually two neutrons.
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.
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.
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.
Charge-mass ratio of a proton?
Mass of a Proton = 1.6726x10-27 kg Mass of a Neutron = 1.6749x10-27 kg The ratio is then: 0.99864
What happens if a free electron and a free proton are put into an electric field?
The proton will have greater acceleration. This is because the proton has a higher charge to mass ratio than the alpha particle. The proton has a +1 charge, as you know, and the alpha particle has a +2 charge because it has 2 protons in it. But the alpha particle also has a pair of neutrons fuesed to those 2 protons, so it has a 2 to 4 charge to mass ratio. The proton, with its 1 to 1 ratio of charge to mass, will have a greater acceleration in the same electric field.
How do you find the net charge of an atom?
To find the charge to mass ratio (specific charge) of an atom, you have to find both the charge of the nucleus and the mass of the nucleus charge of nucleus = proton number x charge of 1 proton (1.6x10^-19) mass of nucleus = nucleon number x mass of 1 proton (1.67x10^-27) the you have to divide the charge of the nucleus by he mass of nucleus e.g Q/M the answer should be in C/kg or Ckg^-1
What is The ratio of the specific charge of an electron to that of a positron is?
1:1
The stability of an isotope nucleus depends on the?
Neutron/Proton Ratio
Why atom is neutral particle?
Because proton and nelutron present in nucleus with charges positive and negative while neutron have no charge and proton and electron have same in numbers and the ratio have between electron and is zero. For.eg magnesium have 12 atomic number and proton and are also 12 in magnesium there ratio is 1:1
Charge-to-mass ratio of an electron?
Proton Mass, m = 1.67x10-27 kg Proton Charge, q = 1.6x10-19 C m/q = 1.04x10-8 kg C-1
How to get a ratio?
calculate the ratio between proton&electron
