atom- (physics and chemistry) the smallest component of an element having the chemical properties of the element radioisotope- a radioactive isotope of an element; produced either naturally or artificially deuterium,heavy hydrogen- an isotope of hydrogen which has one neutron (as opposed to zero ne...
isotope (īˈsətōp), in chemistry and physics, one of two or more atoms having the same atomic number but differing in atomic weight and mass number. The concept of isotope was introduced by F. Soddy in explaining aspects of radioactivity; the first stable isotope (of neon) was disco...

There are 275 isotopes of the 81 stable elements available to study. This is the definition of an isotope along with examples.
238U →234Th →234mPa → ... →206Pb Uranium-238 is the parent isotope, while thorium-234, protactinium-234m, and lead-206 are all daughter isotopes. Daughter Isotopes and Half-Life The half-life of an isotope is used to predict the time half of a sample will decay into a daughter ...
I believe the definition you found may have been a little bit misleading. Here is another definition of isobar I found: each of two or more isotopes of different elements, with the same atomic weight. ... Eli Jones 2,010 answered Nov 16, 2018 at 0:49 11 votes Why are isotopes ...

Stable isotope analysis is still a developing technology, but one that is well suited for forensic investigations, as it is grounded in the foundations of chemistry and physics, in addition to decades of peer-reviewed basic and applied research. The identification of unknown decedents will remain ...
Definition Two nuclides, e.g., 16O and 18O, are isotopes of the same element (here oxygen), if their nucleus has the same number of protons (same charges) but a different number of neutrons (different mass numbers). Because their electronic shells must balance the nuclear charge, ...
