how are alpha and beta particles different?
476449
The alpha particle is a helium nucleus; it consists of two protons and two neutrons. ... Alpha particles are therefore positively charged particles moving at high speeds. Beta particles are emitted by neutron rich unstable nuclei. Beta particles are high energy electrons.
903898
Beta radiation consists of high-energy electrons emitted from the nucleus. These electrons have not come from the electron shells or energy levels around the nucleus. Instead, they form when a neutron splits into a proton and an electron.

Beta particles are negatively charged so they will be attracted towards a positively charged plate . And positive alpha particles will be attracted towards a negatively charged plate. Because they consist of charged particles, alpha and beta radiation can also be deflected by magnetic fields .

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.

Beta Particles in an electric field Beta particles are attracted to the positively charged plate. This confirms that they are negatively charged. Beta particles are fast moving electrons with a very low mass and so have a high charge to mass density. They are deflected much more than the heavier alpha particles.

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 .

Alpha particles (a) are composite particles consisting of two protons and two neutrons tightly bound together (Figure 1). They are emitted from the nucleus of some radionuclides during a form of radioactive decay, called alpha-decay.
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.

Forces on a charged particle. ... And positive alpha particles will be attracted towards a negatively charged plate. Because they consist of charged particles, alpha and beta radiation can also be deflected by magnetic fields . Just as with electric fields, gamma radiation is not deflected by magnetic fields.

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.

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.

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.

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 .

Yes. An alpha particle is a helium nucleus which consists of two protons and two neutrons. This is nearly four times heavier than a neutron by itself. An alpha particle consists of 2 neutrons and 2 protons.

Alpha particles are are positively charges particles that are made up of 2 protons, 2 neutrons and zero electrons. Due to the fact that protons have a +1 charge and neutrons hold no charge, this would give the particle a +2 charge over all. ... This in turn either deflected the particle or adjusted its path.

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.
