Let’s discuss about isotopes with some common examples.
Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.There are over forty such techniques, each using a different radioactive element or a different way of measuring them.Hence, the sum of number of proton and neutron is known as mass number.The number of neutrons, N, is known as the number of neutrons in an atom.Thus, The mass of protons and neutrons have approximately same, hence the atomic mass of an atom is equal to A.
On the basis of atomic number and mass number, elements can be classified as isotopes, isobars and isotones.Approximately 50 of these are found in nature; the rest are produced artificially as the direct products of .Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes. Has there been any way to express the number of protons in an atom? Protons and neutrons are also known as the nucleons.Since an atom having no charge, means the number of electrons must be equal to the number of protons that is the atomic number.), however, is a radioactive isotope, the other two being stable.
