WebMonoisotopic elements. In normal materials, there are nineteen (19) elements whose standard atomic weight is determined by only one isotope, which is also stable (non-radioactive). note Thus, the standard atomic weight for these elements is invariant. These elements are: Be, F, Na, Al, P, Sc, Mn, Co, As, Y, Nb, Rh, I, Cs, Pr, Tb, Ho, Tm, and Au ...
