what is radioactive disintegration?
Asked by shekhar14351 | 30 Jan, 2010, 12:28: PM
answered-by-expert Expert Answer

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 a α - particle is emitted by a nucleus, the mass of the nucleus decreased by 4 units and the charge by 2 units.
