What Is Alpha Decay

Alpha decay is a form of radioactive decay in which an alpha particle is emitted by a heavy element in an attempt to become more stable. When an element undergoes alpha decay its atomic number decreases by two.

Particle detectors can be used to detect the emission of alpha particles and the process of alpha decay can also be used to build detection devices.

What is alpha decay. When an atomic nucleus releases an alpha particle the atom decays is transformed into another atom with a mass number that is lower by 4 and an atomic numberthat is lower by 2. In alpha decay shown in fig. The other types of radioactive decay are beta decay and gamma decay.

Alpha decay is the spontaneous radioactive decay where an alpha particle is produced. Alpha decay or α decay and also alpha radioactivity represents the disintegration of a parent nucleus to a daughter through the emission of the nucleus of a helium atom. An alpha particle with its two protons and two neutrons is a very stable configuration of particles.

Here the atomic mass number of the newly formed atom will be reduced by four and the atomic number will be reduced by two. Alpha decay or α decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle helium nucleus and thereby transforms or decays into a different atomic nucleus with a mass number that is reduced by four and an atomic number that is reduced by two. Alpha decay is a quantum tunneling process.

An alpha particle is essentially a helium nucleus or he 2 ion. Alpha decay type of radioactive disintegration in which some unstable atomic nuclei dissipate excess energy by spontaneously ejecting an alpha particle. 3 3 the nucleus emits a 4he nucleus an alpha particle.

In order to be emitted the alpha particle must penetrate a potential barrier. Because alpha particles have two positive charges and a mass of four units their emission from nuclei produces daughter nuclei having a positive nuclear charge or atomic number two units less than their parents and a mass of four units less. Alpha decay the radioactive decay of an atomic nucleus by emission of an alpha particle two protons bound to two neutrons.

Alpha decayoccurs most often in massive nuclei that have too large a proton to neutron ratio. Alpha decay or α decay is a type of radioactive decay in which the atomic nucleus emits an alpha particle thereby transforming or decaying into a new atomic nucleus. Alpha decay is a form of nuclear fissionin which the parent atom splits into two daughter products.
