what is the difference between an alpha particle and a beta particle?
447
Alpha particles are released by high mass, proton rich unstable nuclei. The alpha particle is a helium nucleus; it consists of two protons and two neutrons. ... Beta particles are emitted by neutron rich unstable nuclei. Beta particles are high energy electrons.

Unlike alpha and beta particles, which have both energy and mass, gamma rays are pure energy. Gamma rays are similar to visible light, but have much higher energy. Gamma rays are often emitted along with alpha or beta particles during radioactive decay.

Alpha particles (α) are positively charged and made up of two protons and two neutrons from the atom's nucleus. ... Alpha particles lack the energy to penetrate even the outer layer of skin, so exposure to the outside of the body is not a major concern. Inside the body, however, they can be very harmful.

Alpha particles are energetic (fast) helium nuclei, beta particles are smaller and have half the charge, being energetic electrons (or positrons) only the gamma particles are photons, i.e., they are not massive particles at all, they are a form of electromagnetic radiation, a form more energetic than X-rays.

An alpha particle is identical to the nucleus of a helium-4 atom, which consists of two protons and two neutrons. ... It is the most common form because of the combined extremely high nuclear binding energy and a relatively small mass of the alpha particle.

FYI: Beta and gamma radiation are also dangerous; they both chip away at DNA and damage living tissue. However, beta particles are smaller, move faster, and have less charge than alpha particles—they are less damaging than alpha particles by a factor of 1000. Gamma radiation is pure energy and has no mass or charge.

Alpha and beta rays are deflected in opposite directions in a magnetic field because they are oppositely charged—alpha are positive and beta negative. ... The alpha particle has twice the charge, but almost 8000 times the inertia (since each of the four nucleons has nearly 2000 times the mass of an electron).

Beta particles are high energy electrons. These electrons are not electrons from the electron shells around the nucleus, but are generated when a neutron in the nucleus splits to form a proton and an accompanying electron. Beta particles are negatively charged. ... Gamma rays have no electrical charge associated with them.

Beta particles are a type of ionizing radiation and for radiation protection purposes are regarded as being more ionising than gamma rays, but less ionising than alpha particles. The higher the ionising effect, the greater the damage to living tissue.

It contains no electrons to balance the two positively charged protons. Alpha particles are therefore positively charged particles moving at high speeds. Beta particles are emitted by neutron rich unstable nuclei. ... Beta particles are negatively charged.

Alpha particles have twice the charge and quadruple the mass of protons. A proton is a subatomic particle with a charge of +1. ... Alpha particles are emmited from larger nuclei during radioactivity decay. Thus alpha particles carry more energy than a proton found inside a nucleus.
268815
An alpha particle is produced by the alpha decay of a radioactive nucleus. Because the nucleus is unstable a piece of it is ejected, allowing the nucleus to reach a more stable state. ... In fusion, helium/alpha particles are produced by the fusion reaction, along with neutrons.

Alpha particles are the heaviest and most highly charged of the nuclear radiations. Without additional energy input, these characteristics make alpha particles less penetrating than beta particles and gamma rays.

It contains no electrons to balance the two positively charged protons. Alpha particles are therefore positively charged particles moving at high speeds. Beta particles are emitted by neutron rich unstable nuclei. ... Gamma rays are emitted by most radioactive sources along with alpha or beta particles.

Alpha radiation is the name for the emission of an alpha particle in fact an helium nuclei, beta radiation is the emission of electrons or positrons , and gamma radiation is the term used for the emission of energetic photons.
16147
Alpha particles have low penetrating power largely because they are immensely more massive than beta, gamma, or neutron radiation. An alpha particle is two protons and two neutrons – a helium atom minus the electrons. ... An electron strikes something sooner, and an alpha readily strikes one of the nearest obstacles.

The alpha particle is a helium nucleus; it consists of two protons and two neutrons. ... Gamma rays are emitted by most radioactive sources along with alpha or beta particles. After alpha or beta emission the remaining nucleus may still be in an excited energy state.
