Concept of Radioactive Decay

Science > Physics > Nuclear Physics > Concept of Radioactive Decay Transformation of radioactive element into another element (radioactive or non-radioactive) is known as radioactive decay or disintegration. In radioactive decay, the nucleus of a radioactive element called parent undergoes a spontaneous change accompanied by the emission of radiation and the formation of the nucleus […]
