Isotopes and it's uses

Isotopes of Hydrogen:

1. Protium: It has on e proton and no neutron in its nucleus. Its atomic number and mass number both are 1. It is denoted by
2. Deuterium: It has one proton and one neutron in the nucleus. Its atomic number is 1 and mass number is 2. It is denoted by
3. Tritium: It has one proton and two neutrons in the nucleus. Its atomic number is 1 and mass number is 3. It is represented by

Isotopes of Oxygen:

Oxygen has also got three isotopes. The atomic number of oxygen is 8. It means all the three isotopes of oxygen have 8 protons but they have 8, 9 and 10 neutrons in their nuclei having mass numbers 16, 17 and 18 respectively. They are represented as:



Isotopes of Carbon:

Carbon has three isotopes. the atomic number of carbon (C) is 6. However the mass numbers of C are 12, 13 and 14. It means all of them have 6 protons but the number of neutrons are 6, 7 and 8 respectively.



Isotopes of Uranium:

There are three common isotopes of uranium. Their atomic numbers are the same, i.e. 92 but their mass numbers are 234, 235 and 236 respectively. They are represented as




Isotopes of Chlorine:

Chlorine has two isotopes. Their masses are 35 and 37. Both the isotopes of chlorine have atomic number 17 it means that each chlorine atom has 17 protons. Cl-35 has18 neutrons and Cl-37 has 20 neutrons. They are are represented as:



Uses of Isotopes:

1. They are used as tracers in physical, chemical and biological researches.
2. They are used in the diagnosis and treatment of diseases like cancer.
