Do alpha prarticle share the same atomic number?
An alpha particle is, essentially, a helium nucleus.This means that is has the same atomic number (no. of protons) as Helium does - it just doesn't have the electrons as well.So the atomic number of an alpha particle would be 2.It's also not neutral, and would have a 2+ charge.The mass number of an alpha particle would be 4 as it has 2 neutrons and 2 protons.All alpha particles are helium nuclei, so they all share the same properties.
Do carbon and oxygen have the same atomic mass?
They don't contain the same number of particles because some particles are more dense than others making one atom and another atom the same mass but not have the same number of particles.
Why did Rutherford use alpha particles rather than electrons for his scattering experenment?
Rutherford used alpha particles because they have more mass and positive charge compared to electrons, making them more suitable for studying the size and charge distribution of the atomic nucleus. The greater mass of alpha particles led to less deflection when they interacted with atoms, allowing Rutherford to better understand the structure of the atom by observing the scattering patterns.
What element has 12 alpha particles and 4 neutrons?
Mathematically it is Chromium 24Cr52 but within nucleus alpha particles separately do not exist they are only produced during radioactive disintegration.
What is the mass in amu of alpha particles?
The mass of an alpha particle is approximately 4 amu (atomic mass units).
What is the mass and charge of alpha particles?
Alpha particles are helium nuclei and consist of two protons and two neutrons. Their electric charge is +2 (+1 from each proton), and their mass number is 4, one for each proton and neutron. To describe their mass in other ways, it is 4.001506179125 atomic mass units, or 6.64465675 x 10-25 kg.
What change in atomic number occurs when a nucleus emits an alpha particles?
An alpha particle has 2 protons and 2 neutrons. This would make the atomic number decrease by 2 and the Atomic Mass will decrease by 4.
What is the greatest amount of mass a radioisotopes emits?
The amount of mass a radioisotope emits is typically very small, on the order of atomic or subatomic particles such as alpha or beta particles. These emissions do not significantly affect the overall mass of the radioisotope.
Alpha particles are repelled by atomic nuclei because?
Alpha particles are repelled by atomic nuclei because alpha particles have a positive charge, and so do atomic nuclei. The positive charge on the surface of a nucleus will repel another positive charge, like an alpha particle, because of the law of electrostatics. That's the simple answer. And it is correct. But know this: Alpha particles were used in the early investigations of atomic structure and atomic interactions. The alpha particles were used to bombard atomic nuclei, and there are times when an alpha particle will be absorbed by an atomic nucleus. Somehow the laws of electrostatics took the day off, and the fact that absorption took place opens the door to discovery and discussion of other atomic forces. Word up.

How did the result of gold foil experiment lead Rutherford to recognize the existence of atomic nuclei?
By beaming alpha particles through gold foil and witnessing some of them deflecting, there had to be a mass larger than an alpha particle in the atomic structure. This disproved the plum pudding theory of the atom, as electrons would not have had enough mass to deflect the larger alpha particles.
What is the effect on the mass number and change of a nucleus when it loses alpha particles?
The mass number goes down by 4, and the atomic number goes down by 2 when a nucleus loses an alpha particle. XYZ --> alpha emission --> X-2Y-4Q + 24He2+
What is the unit for the mass of atomic particles?
Atomic Mass Unit (amu)
What type of nuclear radiation has a mass of 4?
Alpha particles are a type of nuclear radiation with a mass of 4 atomic mass units. They consist of two protons and two neutrons bound together.
How many particles do alpha particles contain?
Beta particles have an electrical charge of -1. Beta particles have a mass of 549 millionths of one atomic mass unit, or AMU, which is about 1/2000 of the mass of a proton or neutron.
Mass of alpha particle?
The mass of an alpha particle is 4 atomic mass units, 2 protons and 2 neutrons, or about 6.644656 x 10-27 kg.
