explain radioactivity with an example
Answers
Answer:
Definition -
the phenomenon, exhibited by and being a property of certain elements, of spontaneously emitting radiation resulting from changes in the nuclei of atoms of the element.
The process of emission of particles from nuclei because of the nuclear instability; is known as radioactivity.
The process of emission of particles from nuclei because of the nuclear instability; is known as radioactivity.The substance that releases such energy/rays is known as radioactive substance.
The process of emission of particles from nuclei because of the nuclear instability; is known as radioactivity.The substance that releases such energy/rays is known as radioactive substance.The invisible rays released from such radioactive substance are known as radioactive rays.

Example -
One example of a radioactive substance is uranium. In nuclear power plants, uranium is used to produce electricity. When radioactive substances like uranium produce radiation, they also create a lot of heat.

Radioactivity is the spontaneous emission of radiation in the form of particles or high energy photons resulting from a nuclear reaction.
