Respuesta :
The process in which the nuclei of unstable atoms can become more by emitting particles or electromagnetic radiation is called radioactive decay.
In the process of radioactive decay an unstable atomic nucleus loses energy by electromagnetic radiation.This involves transformation of one element into another by changing the number of protons in the nucleus.It is the emission of energy in the form of radiation. This occurs due to instability of nucleus.emission of energy in the form of radiation.
Radioactivity is a source of heat.It causes a huge amount of energy released into the surrounding in the form of ionising radiation.This includes alpha ,beta and gamma rays.
After undergoing radioactive decay,it tends to transform into the atom of some other elements known as decay products.
