Answer to Question #10464 in Inorganic Chemistry for Mona

Question

Tell me the elements which don't have isotopes?

Answer 1

Isotopes are variants of a particular chemical element. While all isotopes of a given element
share the same number of protons, each isotope differs from the others in its number
of neutrons. There are stable and radioactive isotopes. Chemical elements, as a rule, are a
mixture of isotopes- atoms with identical serial numbers (charges), but different mass numbers.
The greatest number of isotopes has a tin (Z = 50) with xenon (Z = 54), nine isotopes, cadmium
(Z = 48) and tellurium (Z = 52) each have eight isotopes, other elements have a smaller number
of isotopes. There are elements that have only one stable isotope, and they are simple. There
are F, Na, P, V, Mn, Au, Be,Al.
