alpha decay of uranium

Alpha decay is the phenomenon of emission of an a - particle from radioactive nucleus...

. The first natural series to be discovered is uranium - 238 series. It involves fourteen separate steps, eight of which involve a - emission whereas six involve b - emission. The overall process is written ..

A radioactive nucleus or element emits an alpha or a beta particle and gets converted into a new nucleus or element. The process of destruction of the original nucleus during the formation of new nucleus due to radioactivity is called Radioactive decay or disintegration. When..

Summary - When certain metals are heated to a high temperature, they emit thermions (electrons) and the phenomenon is called thermionic emission Cathode rays are a stream of negatively charged particles emitted from the cathode of an evacuated bulb, when a voltage of nearly 3000 volts given across ..

. A g -ray photon has no rest mass and no charge. According to radioactive decay law, Where l is disintegration constant. Half life of a radioactive element is the time during which half the total number of atoms in the element (N 0 ) disintegrate, i.e., in Average life or mean life of ra..

The discovery of the phenomenon of radioactivity was purely accidental. In 1896, Henry Becquerel, a French scientist accidentally found that in presence of salt of uranium, photographic plates got heavily fogged even though they were wrapped in opaque paper. He concluded that the ura..
