An Alpha particle is composed of two protons and two neutrons, so simplisticly it is heavier than one neutron by the mass of two protons and one neutron. A proton weighs in at 1.672621777(74)×10−27 kg and a neutron a bit more at
1.674927351(74)×10−27 so you can do the maths if u want to see the actual figure.
Alpha particles (helium nuclei) are much larger and heavier than beta (electrons) and gamma (high-energy photons). This means they do far more damage to anything they hit. However, it also means can't travel very far and can be stopped by as little as a sheet of paper. Radioactive isotopes that emit only alpha radiation are not very dangerous, the only danger is breathing in or ingesting the isotope.
No, an alpha particle is not identical to an electron. An alpha particle is a helium-4 nucleus, and it's composed of a pair of protons and a pair of neutrons fused together. It several thousand times the mass of an electron, and has twice its charge with an opposite sign (+2). An electron is that little negatively charged (-1) elementary particle that we find whizzing around atoms. You'll find a pair of related questions linked below.
Alpha particles with the same energy as beta particles have much less speed, magnetic field or no.
The particle that carries the positive charge (a proton) is much more massive than the particle that carries the negative charge (an electron) The charges are equal in magnitude though of opposite polarity.
This depends on the velocity, or temperature, of the alpha particle. The faster the particle goes, the higher its temperature, and the more energetic it is. When we are dealing with atoms and subatomic particles, temperature and velocity are pretty much measurements of the same thing. Most alpha particles emitted from large radioactive atoms have energies in the range of 3 to 7 MeV (million electron volts). Alpha particles from the decay of the heavier, man-made atoms can be more energetic yet. 5 MeV would mean that the particle is going about 15,000 km/s, or about 5% of the speed of light. At that speed, the alpha particle can be absorbed by a piece of thin paper. They are not horribly dangerous, if the particles are outside you. But if they are emitted from something inside you, they can be very destructive because they can alter living cells. It should be noted that an alpha particle is essentially the same thing as a Helium-4 nucleus. The difference is that the alpha particle came from nuclear decay, and is moving.

The alpha particle is much more massive than a beta particle. A beta particle is an electron, which has very little mass. An alpha particle is a helium nucleus, and consists of two protons and two neutrons.

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 neutron has a mass that is nearly equal to the combined mass of a proton and an electron. This is due to the fact that the neutron is slightly heavier than the proton, while the electron has a much smaller mass.
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.

The electron is actually the smallest particle. The neutron is the largest particle, followed closely by the proton. The electron is much, much smaller.
They are much denser. it's the same with stars and neutron stars. Neutron stars are many times smaller than the original star but much heavier because they are so denser
No, a neutron is slightly more massive than a proton. Both particles have roughly the same mass, but due to the different composition of their internal quarks, the neutron is slightly heavier.
