Charge to mass ratio of electron?
The charge to mass ratio of an electron is approximately -1.76 x 10^11 coulombs per kilogram. This means that electrons have a very small mass compared to their charge. This value was first measured by J.J. Thomson in his experiments with cathode rays.
Why is the magnetic moment of a nucleus smaller than the magnetic moment of an electron?
The magnetic moment of a nucleus is generally smaller than that of an electron because the nucleus is composed of protons and neutrons, which have smaller individual magnetic moments that partially cancel each other out due to their arrangement within the nucleus. Electrons, on the other hand, are elementary particles with a specific magnetic moment that is not cancelled out by other particles.
Is Specific charge is scalar or vector?
specific charge is because a physical quantity can be complete only when by giving magnitude only. Here the physical quantity is complete by its magnitude.
How does an atom that loses electrons such as in beta decay end up with a different atomic number?
When the number of protons in the nucleus is changed, and an electron or positron created, the atom undergoing decay becomes, in effect, a different element. The number of protons is what determines the elemental status of an atom.In beta decay, a neutron becomes a proton and the nucleus releases an electron and antineutrino.In beta+ decay (aka positron emission), a proton becomes a neutron, releasing a positron and antineutrino. In each case, the decay changes the neutron/proton ratio and makes the atom more stable.
Charge-to-mass ratio of an electron?
The charge-to-mass ratio of an electron is approximately 1.76 x 10^11 coulombs per kilogram. This value is a fundamental characteristic of electrons and is used in various physics applications, such as in particle accelerators.
What is ratio of specific charge of an electrorn to that of proton?
The specific charge of an electron is 1.759 x 10^11 C/kg, while the specific charge of a proton is 9.58 x 10^7 C/kg. Therefore, the ratio of specific charge of an electron to that of a proton is approximately 1.8 x 10^3.
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.
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 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 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.
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.
Which atom has the highest charge to mass ratio?
The electron has the highest charge to mass ratio. This is because it has a tiny mass compared to its charge, making its ratio very high.
How do positron emission and electron capture change an atom?
Positron emission results in the atom losing a proton, transforming the atom into a different element with a lower atomic number. Electron capture involves the atom gaining a proton, resulting in the transformation of the atom into a different element with a higher atomic number. Both processes lead to the formation of a more stable nucleus by adjusting the ratio of protons and neutrons.
What is the amount of current per second?
Ratio of charge of electron to 60 will be the amt. Of current.
Charge to mass ratio of electron?
The charge to mass ratio of an electron is approximately -1.76 x 10^11 coulombs per kilogram. This means that electrons have a very small mass compared to their charge. This value was first measured by J.J. Thomson in his experiments with cathode rays.
Millikans oil drop apparatus allowed for the determination of which property of the electron?
Millikan's oil drop apparatus allowed for the determination of the charge of the electron. By measuring the charges on oil droplets and manipulating electric fields, he was able to calculate the charge-to-mass ratio of the electron, which in turn helped determine the actual charge of the electron.
Why is the magnetic moment of a nucleus smaller than the magnetic moment of an electron?
The magnetic moment of a nucleus is generally smaller than that of an electron because the nucleus is composed of protons and neutrons, which have smaller individual magnetic moments that partially cancel each other out due to their arrangement within the nucleus. Electrons, on the other hand, are elementary particles with a specific magnetic moment that is not cancelled out by other particles.
