  • Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties. Every chemical element has one or more isotopes. •Mar 11, 2019 · If you are performing calculations using a molecule that contains a specific isotope, use its mass value. This will be the sum of the masses of its protons and neutrons. For example, if all the hydrogen atoms in a molecule are replaced by deuterium, the mass for hydrogen would be 2.000, not 1.008.

    An isotope is a variant of an element in which it has an equal number or protons but a varied number of neutrons. The notation of an isotope occurs by adding a subscipt and superscript to the left side of an element such as 238 92U (uranium isotope)
