Solution
The correct option is B False
The given statement is false.
The isotopes of elements with the atomic number(Z) less than 82 are said to be radioisotopes. The nucleus of an atom becomes radioactive when the number of neutrons exceeds the number of protons in the nucleus. They undergo radioactive decay and are also known as the 'Unstable isotopes'. The stability of the atoms of different elements is dependent on their nuclear binding energy. If the nuclear binding energy of an atom is more than the repulsive forces between the nucleons, it is stable; else unstable.
