Heavier isotopes of the same element react more slowly than lighter isotopes of the same element
True
Twenty-six elements are there which have only one stable isotope which is called ____?
Monoisotopic
A distinct kind of atom with a specific number of neutrons and protons. Can be uncategorized as, isotopes, isotones, and isobars.
Nuclide
A nuclide with the same number of neutrons (N), but a different number of protons (Z)
Isotone
A nuclide with the same mass number (A), but a different number of neutrons (N) and protons (Z)
Isobar
Spontaneous breakdown of large nuclei into two smaller nuclei
Spontaneous fission
Process of spiking a sample with a known quantity of one or more tracer isotopes in order to convert ratios measured by mass spec to moles in sample isotope, reference is most abundant isotope
Isotope dilution
