Why is the magnetic moment of a nucleus smaller than the magnetic moment of an electron?
Because the charge/mass ratio of a nucleus is smaller than the charge/mass ratio of an electron
What is The ratio of the specific charge of an electron to that of a positron is?
1:1
Charge to mass ratio of electron?
1.759 x 1011 Coulomb per Kilogram
What is the relationship between radius ratio and coordination number in crystal packing?
r+ / r- that is the ratio of radii + charge to -charge gives a ratio this ratio is used to determine the CN the table is given a lot of books
Why were J.J Thomson's discoveries important?
JJ Thomson did pioneering work in physics, which has been useful in continuing scientific and technological developments. These include work with cathode ray tubes leading to the identification of the electron (he called them corpuscles), mass spectrometry where he was the first to demonstrate isotopes of an element (neon 20 and 22), and the demonstration of Thomson scattering of electromagnetic radiation by charged particles.
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 a Cathode ray gun?
basically JJ Thomson wanted to find out what a cathode ray was made of. Cathode tubes are a tube with wires in them. Scientists discovered that if the created a vacuum in the tube and sent a charge through the wires, it glowed. JJ Thomson set up a cathode ray and placed magnets on either side. This deflected the ray so the tube didn't glow. This meant the rays were negatively charged which meant they were made of negatively charged particles or electrons.
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 is the magnetic moment of a nucleus smaller than the magnetic moment of an electron?
Because the charge/mass ratio of a nucleus is smaller than the charge/mass ratio of an electron
What is The ratio of the specific charge of an electron to that of a positron is?
1:1
What did thomson's cathode ray tube experiments help scientists learn?
Thomson's cathode-ray tube experiments helped scientists learn about electrodes and that atoms were comprised of many small particles, which they did not know existed. They also learned from this tube that all the electrons were the same regardless of what elements they came from.
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?
1.759 x 1011 Coulomb per Kilogram
What is the relationship between radius ratio and coordination number in crystal packing?
r+ / r- that is the ratio of radii + charge to -charge gives a ratio this ratio is used to determine the CN the table is given a lot of books
What did the cathode ray tube tell us about atomic structure?
because Thomson saw the ray move from the cathode to the anode so the particles have negatively charge
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.
