An alpha particle is about four times heavier than a proton.
When an alpha particle (helium nucleus) is emitted by a nucleus, the proton number decreases by 2 and the mass number decreases by 4. This is because the alpha particle consists of two protons and two neutrons.
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.
A particle that has a mass of 1 and a charge of 1 plus is a proton.
The electron is the lightest particle in the list. A proton is 1836 times more massive than an electron. Neutrons are just slightly more massive than a proton, and an alpha particle consists of two protons and two neutrons.
No, an alpha particle has a mass of 4 amu and a charge of +2. It is a helium nucleus. The neutron has a mass of 1 amu and no charge.
No, an alpha particle is the nucleus of a normal helium atom - 2 protons + 2 neutrons. Therefore, an alpha particle has approximately 4 times the mass of a proton or neutron.No, an alpha particle is the nucleus of a normal helium atom - 2 protons + 2 neutrons.

An alpha particle has approximately 4 times the mass of a proton.
The mass and size of an alpha particle compare with the masa and size of beta particle in the sense that the alpha particle is significantly larger in both size and mass that the beta and gamma particles. This is why it is called the alpha particle.
The correct order of the particles based on increasing mass is electron, proton, alpha particle. Electrons are the lightest of the three, followed by protons, and then alpha particles, which consist of two protons and two neutrons and are relatively heavier.

No. Its not even close. An alpha particle is two neutrons and two protons, while a beta particle (from beta- decay) is just an electron, which has one 1836th the mass of a proton.
among these Electron has the least mass....
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.
The mass of an alpha particle is approximately 4 atomic mass units (AMU), which is equivalent to 4 times the mass of a proton. In a nuclear equation, an alpha particle is represented as ( ^4_2 \text{He} ), indicating a mass number of 4 and an atomic number of 2.
An alpha particle is a helium nucleus, consisting of 2 protons and 2 neutrons. Beta particles are fast moving electrons that are emitted from a nucleus when a neutron decays into a proton and an electron. Since 1 electron has 1/1837 the mass of a proton, the alpha particle is roughly 7348 times the mass of the electron.
They both have about the same mass. However, since a proton is made of three up-quarks and the neutron is made of two up-quarks and a down-quark, the neutron is slightly more massive than the proton (around 0.3% more massive).
An alpha particle is a helium-4 nucleus. It has a mass of about 4 atomic mass units.
