what is the difference between alpha particle and 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.
1404689
An alpha particle is identical to a helium atom that has been stripped of its two electrons; thus, an alpha particle contains two protons and two neutrons. ... Thus He2+ means a helium atom that has lost two electrons and has a +2 charge.
949564
Alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium nucleus, which is produced in the process of alpha decay. ... atom is a nucleus + electrons, a helium atom is thus its nucleus (2 protons, 2 neutrons) and its 2 electrons. An alpha particle is just the nucleus.

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.
147873
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.

The ancient greek alphabet was familar to physicists nourished by classical culture. 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.

Alpha radiation consists of alpha particles. An alpha particle is identical to the nucleus of a helium atom, which comprises two protons and two neutrons .
935582
Alpha decay forms new element with two fewer protons and two fewer neutrons; Beta decay forms new element with one more proton and one fewer neutron. ... Gamma radiation has the highest penetration power, Beta decay goes the second, alpha decay the last.
1380537
A beta particle forms when a neutron changes into a proton and a high-energy electron . The proton stays in the nucleus but the electron leaves the atom as a beta particle.
775850
Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus.
1198647
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.

Characteristics of Alpha Particles / Radiation. Alpha particles are energetic nuclei of helium. The production of alpha particles is termed alpha decay. Alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium nucleus.

Difference between Alpha, Beta and Gamma radioactive decay can be summarized as follows: Alpha decay forms new element with two fewer protons and two fewer neutrons; ... Gamma radiation has the highest penetration power, Beta decay goes the second, alpha decay the last.

A nucleus changes into a new element by emitting alpha or beta particles . These changes are described using nuclear equations. Alpha decay (two protons and two neutrons ) changes the mass number of the element by -4 and the atomic number by -2. An alpha particle is the same as a helium-4 nucleus .
1133208
Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus. They are generally produced in the process of alpha decay, but may also be produced in other ways.
672423
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).
136730
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 alpha particle rapidly accumulates the two electrons neccessary the neutralize.
