beta radioactivity

Radioactivity - It is a spontaneous emission or disintegration of an unstable nucleus resulting in certain radiations. The elements exhibiting this phenomena are called radioactive elements. e.g., radium, thorium, actinium, polonium etc. Radioactivity does not occur du..

A phenomenon of emission of an electron from a radioactive nucleus...

Carbon-14 is unstable and decays by beta emissions to nitrogen. Because of the constant production of carbon-14 and its radioactive decay, a small fractional abundance of carbon-14 is maintained in the atmosphere. Living plants, which use carbon dioxide from the atmosphere, also..

Radioactive nuclei being unstable, emit radiations to achieve states of greater stabilit..

A radioactive nucleus or element emits an alpha or a beta particle and gets converted into a new nucleus or elemen..

It is a nuclear phenomenon. It is due to the instability of the nucleus. It is a spontaneous, continuous and irreversible process. It is independent of external factors such as pressure, temperature, state of substance, electrical field, magnetic field, catalyst etc. A radioactiv..

>Three types of radiation from recognized radioactive elements are a -particles, b -particles and g -radiation. It was realized that radioactivity of an element is independent of its physical state, its chemical environment or temperature, suggesting that it is a property of the..

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 d..
