Asked by anjukumarisah730 | 16 Mar, 2023, 10:30: PM
Expert Answer
The isotopes of nearly all the elements of atomic number higher than 82 ( i.e., after lead in periodic table )
are radioactive because in their nucleus, the number of neutrons is much more than the number of protons.
These are called the natural radioactive substances.
