Questions and Answers Alpha rays are actually high speed particles. Early researchers tended to refer to any form of energetic radiation as rays, and the term is still used. An alpha particle is made up of two protons and two neutrons, all held together by the same strong nuclear force that binds the nucleus of any atom.

Alpha-Beta-Gamma radiation Alpha-Beta-Gamma radiation. Alpha and Beta particles are actually physical particles of matter. The Alpha is two protons and two neutrons, and consequently is relatively very heavy and slow and carries a double positive charge.. A Beta is simply an electron and has a negative charge. The Beta may be moving from very slow to very fast, and the speed is an indication of it's energy level. Gamma Radiation is a true electromagnetic energy, and moves at or near the speed of light. Alphas can barely penetrate anything, not even a piece of paper.

Alpha decay Previous (Alpha and Omega) Next (Alpha ray) Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle. An alpha particle (or α particle, named after the first letter of the Greek alphabet) consists of two protons and two neutrons bound together.

It is the type most likely. to collide with other atoms which means that. (i) alpha particles have the least penetrating ability of the three types.

Types of Radioactive Decay Since Alpha particles have two protons and no electrons, they have a net charge of 2+. During Alpha radiation an atom's proton count drops by two, and we know what that means - a NEW element is formed! Alpha radiation can be stopped by PAPER.

Beta Decay Beta particles are electrons or positrons (electrons with positive electric charge, or antielectrons). Beta decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other.eta particles are electrons or positrons (electrons with positive electric charge, or antielectrons).

- The three major subatomic particles of an atom are electrons, neutrons and protons, according to Science Daily. Protons and neutrons are made of smaller particles known as quarks. Photons, positrons and neutrinos are made after nuclear fusion occurs in stars.

Ionizing radiation Alpha particles are a highly ionizing form of particle radiation. When they result from radioactive alpha decay they have low penetration depth. In this case they can be absorbed by a few centimeters of air, or by the skin.

Alpha Decay In alpha decay, shown in Fig. 3-3, the nucleus emits a 4 He nucleus, an alpha particle. Alpha decay occurs most often in massive nuclei that have too large a proton to neutron ratio.An alpha particle, with its two protons and two neutrons, is a very stable configuration of particles.n alpha decay, the atomic number changes, so the original (or parent) atoms and the decay-product (or daughter) atoms are different elements and therefore have different chemical properties.

- The discovery of such a feature was made by Rutherford in his alpha particle experiment. As the majority of alpha particles shot at a thin layer of gold went through it, this suggested that atoms consist mostly of empty space.

- Alpha decay. When an alpha particle is emitted from a nucleus the nucleus loses two protons and two neutrons. This means the atomic mass number decreases by 4 and the atomic number decreases by 2. A new element is formed that is two places lower in the Periodic Table than the original element.

What subatomic particles make up the nucleus of an atom? At the basic level, the nucleus of an atom is made up of protons and neutrons. At the more fundamental level, the nucleus of an atom is made up of quarks and other sub-subatomic particles, such as leptons and gauge bosons. Two down quarks and one up quark make up a neutron, while one down quark and two up quarks make up a proton.

Alpha decay Visual representation of alpha decay. Alpha decay or α-decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle and thereby transforms or 'decays' into an atom with a mass number that is reduced by four and an atomic number that is reduced by two.lpha decay typically occurs in the heaviest nuclides. Theoretically, it can occur only in nuclei somewhat heavier than nickel (element 28), where the overall binding energy per nucleon is no longer a minimum and the nuclides are therefore unstable toward spontaneous fission-type processes.

- H-alpha (Hα) is a specific deep-red visible spectral line in the Balmer series created by hydrogen with a wavelength of 656.28 nm, which occurs when a hydrogen electron falls from its third to second lowest energy level.herefore, the H-alpha line occurs where hydrogen is being ionized. The H-alpha line saturates (self-absorbs) relatively easily because hydrogen is the primary component of nebulae, so while it can indicate the shape and extent of the cloud, it cannot be used to accurately determine the cloud's mass.

Radioactivity Beta particles are emitted by neutron rich unstable nuclei. 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.

Alpha particle Alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium nucleus. They are generally produced in the process of alpha decay, but may also be produced in other ways.Alpha particles are named after the first letter in the Greek alphabet, α. higher energy version of alphas than produced in alpha decay is a common product of an uncommon nuclear fission result called ternary fission. However, helium nuclei produced by particle accelerators (cyclotrons, synchrotrons, and the like) are less likely to be referred to as alpha particles.
