They are Helium nucleii so basically 2 protons and 2 neutrons
No, alpha particles are helium nuclei made up of two protons and two neutrons, with no electrons. In Rutherford's experiment, alpha particles were used to probe the structure of atoms by scattering off the positive nucleus, helping to reveal the atom's structure.
Alpha particles are most commonly found when alpha decay occurs. An alpha particle is emitted during alpha decay. Further information about alpha particles can be found on the Wikipedia website.
Beta particles have a negative charge, while alpha particles have a positive charge. Beta particles are electrons or positrons, while alpha particles are helium nuclei consisting of two protons and two neutrons.
Alpha particles can be blocked by a block of lead due to their relatively low penetrating power, while beta particles may require a thicker shield, such as a piece of aluminum or plastic, depending on their energy. Lead is not as effective at blocking beta particles as it is for alpha particles.
Plutonium is especially an alpha particles emitter.

No, they're just similar to a helium nucleus.
Yes, plus 2 neutrons.
Alpha particles can be absorbed by water.

Alpha particles consist of two protons and two neutrons (the nucleus of a helium atom). Therefore, Hydrogen is the only element that doesn't contain (and can't emit) an alpha particle.
Alpha decay is the type of radioactive decay in which positive particles, specifically alpha particles, are emitted. These alpha particles consist of two protons and two neutrons bound together, giving them a positive charge.
some of alpha particles were deflected through an angle of 90 degree
It often contains Iodine when used in bread and baking. But sometime irradited salts contain alpha particles

Beta particles have a negative charge, while alpha particles have a positive charge. Beta particles are electrons or positrons, while alpha particles are helium nuclei consisting of two protons and two neutrons.
The symbol of the alpha particle is the small Greek letter alpha, α
