Question

Give two applications of Isotopes.

Answer 1

Isotopes:

1. Different forms of an an element having same atomic number but different mass number.
2. They have equal number of protons.
3. Number of neutrons is different in isotopes.
4. They have similar chemical properties but different physical properties.
5. Example : ${}_6{}^{12}\mathrm{C}\mathrm{and}{}_6{}^{13}\mathrm{C}\mathrm{are}\mathrm{the}\mathrm{isotopes}\mathrm{of}\mathrm{carbon}.$

Two applications of Isotope:

1. Cobalt-60 is useful in the diagnosis and treatment of cancer.
2. Hydrogen-3 is used to study life science and drug metabolism.
