Mass of alpha beta gamma?
Well mass of alpha is 4 but i don't know the other two, sorry The mass for alpha beta and gamma are ... alpha=4 beta=1/200 gamma=0 :)
How does the mass of an electron compare to the mass of a proton and neutron?
The proton mass is about 2,000 times greater than the electron mass.
If a proton had a mass of 1 what is the mass of an electron and neutron relative to the mass of the proton?
If a proton would be 1, an electron would be 0.000544. An electron is 1,836 times lighter than a proton. A neutron would be 1.001 as a proton is 99.86% the mass of a neutron
What are the mass and charge for each sub-atomic particle?
In the atom: Neutron: Mass: 1,00866491600(43) amu. Electron: Mass: 5,4857990946(22)×10−4 amu. Proton: Mass: 1,007276466812(90) amu.
Electron and protons mass?
Answer*Relative Mass*Protons have a relative mass of 1 compared to neutrons.Neutrons have a relative mass of 1 compared to protons.Electron =5.45 x 10-4
How do you find the momentum of an electron when it is moving with a speed of 0.75c?
The momentum in special relativity is given by the following formula: p = gamma*m*c^2 where c is the speed of light, m is the mass of (in this case) the electron and gamma is the so-called gamma factor, which is: gamma = 1/sqrt(1-(v/c)^2) where v is the speed of the electron. Using v = 0.75c we have for gamma: gamma = 1/sqrt(1-0.75^2) which is about 1.5. Thus we have: p = 1.5*m*c^2.
The mass of neutrons and electrons are about the same?
No. The mass of neutrons and protons are about the same. The mass of an electron is about 1/1800th the mass of a proton.
What is the size of electron proton and neutron?
The electron is the smallest having about 1/1836th the mass of a proton or neutron, which means that basically an electron has no mass. The neutron and proton weigh the same both having a mass of 1.
What have almost equal masses to the proton?
No, it isn't. The mass of an electron is significantly smaller than that of a proton.The mass of 1,800 electrons is about the same as the mass of one single proton.The antiparticle of the electron, the positron, has the same mass as the electron.the mass of the electron is not the same to the mass of the 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.
What are some queries about the annihilation process that is given in Wikipedia and Google?
First of all to discuss the definition of annihilation on the Google page. The definition goes as "the conversion of matter into energy, especially the mutual conversion of a particle and an antiparticle into electromagnetic radiation." Here the matter is converted into energy. The matter is converted into energy as per the equation of the Einstein. That means E = m c 2. Here 'c' is the speed of light. That is about 300,000,000 meters/second. The "c" square becomes 90,000,000,000,000,000. So you take the electron as a unit. From this you get 90,000,000,000,000,000 times units of energy. Here you are getting only two gamma rays after collision of the electron and positron pair. That means that from the pair of gamma rays, you should be able to get one electron and one positron. That is very funny. The speed of the electron and positron is about 1 % of that of light. Now the mass-energy must be conserved. So here goes the equation. E = m 1 * 1/100 c * 1/100 c + m 2 * 1/100 c * 1/100 c = gamma ray + gamma ray. Here m 1 is the mass of electron. m 2 is the mass of positron. m 1 = m 2. So E = 2 m * 1/10000 c 2 = 2 gamma rays. Then you get m * 1/10000 c 2 = gamma ray. Gamma ray has got the speed of light. This equation gives the mass of 10,000 photons in gamma rays to be equal to one electron or one positron. That is not correct. Electron is far many times more massive than the photon. In fact the photon is presumed to have zero rest mass. That is also correct that the momentum of the system has to be conserved. Here the equation for the momentum is p = m*v. Here the mass m is equal and same in case of electron and positron. So the equation is p = m * 1/100 c. In case of electron and positron the m is equal and v is equal to 1/100 c. ( c being speed of light.) The gamma ray has got the v equal to the speed of light. Here 100 photons in gamma rays become as massive as electron or positron. That is not correct. Electron or positron are far more massive than photon. In fact the photon is presumed to have zero rest mass.The fact is that electron and positron disappear into nothing. The kinetic energy that is carried by the electron and positron can not be annihilated and is released as pair of gamma rays.The proton and anti-proton is 1836 times as massive than electron or positron. When you put this value in the E = m c 2. Then the energy produced from proton and anti-proton is 1836 times as much as produced from the electron or positron. Here as per the annihilation chapter in Wikipedia, you are getting only 9 to 13 gamma rays. This is not correct and logical. I do not get into detail of this calculations. I am not good at calculations. Only thing I want to point out that you get only two gamma rays from from pair of electron and positron is far much underestimate.Now here goes the theoretical calculation. You convert the entire mass of the universe into energy as per the equation of the Einstein. The equation goes as E = m c 2. So the unit mass will be converted into 90,000,000,000,000,000 units of energy. That is enormous quantity of energy. All the mass is converted into gamma rays. Then from every two gamma rays you get a pair of electron and positron. From 9 to 13 pair of gamma rays you will get the pair of protons and anti-proton and pair of neutrons and anti-neutron.You just calculate the amount of mass that will be produced in the process. It will be enormously high quantity of the mass than the original mass of your universe. There is equal amount of mass of anti-matter. All this newly produced mass can be reconverted into energy again. Again you can get matter and anti-matter from this energy. You can do this cycle end number of times. You can go on creating much more and more mass.Another question is why the conversion of positron and electron into gamma rays is not reversible? That is against the inter conversion of mass and energy. As per the equation of the Einstein, that is E = to m c 2, mass and energy are inter convertible. Energy can be converted into mass and mass can be converted into energy, end number of times. In case of the atomic energy the amount of energy from the mass is enormously high.So equal quantity of matter and anti-matter is produced from nothing and disappear into nothing.here goes the link.What_is_the_theory_of_creation_of_the_matter_and_anti_matter_from_nothing
Why electron don't have mass?
An electron does have mass, but it's so small that it's often considered 0. If the mass of a proton or neutron is 1, then the mass of an electron is about 1/1836.
What is an electron's atomic mass number?
The electron has no atomic mass number. The mass of an electron is roughly 1/1800 of the mass of a proton or neutron.
Relative mass of electron?
1/1840 the mass if a hydrogen atom.
What is the mass of 1 electron?
1/1836 of an electron is the mass of an electron. It is so small they aren't even calculated in the Atomic Mass of an element
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 is the mass and charge of beta particle?
Beta particles are actually electrons (-e) or can be positrons.The mass of one electron or beta particle is 9.1095*10-31 kilograms or 0.000548597 AMU which is about 1/2000 times the mass of a proton or neutron.
