they come from the nuclei of an unstable atom.
Yes alpha particle goes under goes electromagnetic radiations. when an atom is exposed to the magnetic field the alpha particle deviates right through right direction which indicates does have capacity to excite and emits radiations to come to ground level.
The three main types of radiation that can come from radioactive materials are alpha particles, beta particles, and gamma rays. Alpha particles consist of two protons and two neutrons, beta particles are high-energy electrons or positrons, and gamma rays are high-energy electromagnetic radiation. Each type of radiation has different properties and levels of penetration.
Alpha particle has same effect with gamma rays in photographic effect ,both can can blacken a photographic film.And it has same effect with beta particles in the effect of electric and magnetic fields, both are deflected by electric and magnetic fields.
No, alpha, beta, and gamma rays are not all produced by the same element. Alpha particles consist of two protons and two neutrons and are emitted during radioactive decay of heavy elements like uranium. Beta particles are electrons or positrons emitted during the decay of certain isotopes. Gamma rays are high-energy photons emitted during the transition of a nucleus to a lower energy state and are not particles.
In beta- decay, a neutron is converted into a proton, and an electron and an electron antineutrino is emitted. More fundamentally, a down quark is converted into an up quark by the emission of a W- boson. The quark conversion is part of the neutron becoming a proton, and the W- boson subsequently decays into the electron and electron antineutrino.In beta+ decay, a proton is converted into a neutron with the addition of energy, and a positron and an electron neutrino is emitted. More fundamentally, an up quark is converted into a down quark, causing the emission of the electron and electron antineutrino. If the beta+ decay also involves K capture, which is the capture of a K shell electron into the nucleus, then there will be subsequent realignment of the electron shells and emission of photons of various energies (x-ray) as the electrons come back to ground state.

Alpha particles are composed of two neutrons and two protons, so they have a positive charge. When the alpha particles bounced straight back from the gold foil, this indicated that they had hit a particle of like charge, in other words a positively charged particle in the gold foil, which repelled the alpha particle.
The three types of natural radioactivity are alpha, beta and gamma radiation. Gamma rays are the most energetic, and the hardest to shield against as they do not readily interact with shielding material. Alpha and beta radiation are actually particles. The beta particle is an electron that has been released. Because of its mass, it more readily reacts with shielding material, and so cannot penetrate as far. Alpha particles are the largest and consist of two neutrons and two protons. Shielding is most effective against alpha particles. Your outer layer of dead skin or a T-shirt is generally enough to protect against alpha particles. However, this effectiveness of shielding does not mean that gamma is always the most harmful and alpha the least. The high effectiveness of shielding on alpha particles is due to the fact that they most readily react with the shield (i.e. damage it). This means that if the alpha particle is able to come in contact with living tissue (like the ingestion of radioactive liquids) it will do far more damage than a beta particle or gamma ray.

Uranium-238 emits alpha radiation; its half-life is 4,468×109 year.
At its most basic all matter is made up of various quarks. Quarks come in six flavours as both quarks and antiquarks. They form electrons, protons and neutrons. These larger particles form the atoms of all elements.
No they are not in the same way that arms and legs are not people.Protons, neutrons and electrons can come together in some specific numbers form atoms (or molecules). You can also have electrons by themselves. Normally you will not find isolated neutrons and protons. Alpha particles are 2 protons+2 neutrons which are found in radioactive decay.
Alpha particle - (helium nucleus) with a positive charge Beta particle (high speed electron) with a negative charge Gamma ray (electromagnetic radiation) with no charge Radio active decay occurs because the nucleus is unstable. It depends on the particular atom which decay path it will take. A stable atom normally has a few more neutrons than protons. If there are one or two extra neutrons, but not enough to make it stable, getting rid of two of each will slightly increase the proportion of neutrons making it just a little more stable. In this case ALPHA radiation is the result. This consists of helium nuclei with two protons and two neutrons. If there are too many neutrons, one can turn into a proton. When this happens an electron must come into existence by being ejected from the neutron. This is called BETA radiation. If there are too many protons, one of them can eject a positron (positively charged electron) and turn into a neutron. The positron will then very quickly unite with an electron. When this happens they annihilate each other and become very high energy photon (light particle/wave) called a GAMMA ray. This happens mostly in nuclear reactors or in bombs. An example of beta (electron emission) radiation is when Radium 225 loses an electron and turns into Actinium 225 (half life 14.8 days). An example of alpha radiation is when the resulting Actinium loses a helium nuclei or alpha particle to become Francium 221. (half life 10 days) During these processes, other particle called neutrinos are also formed just as they are in the sun. For more about particles check related links below

Alpha is the first letter of the Greek alphabet.
