For each of the elements below,there are only two naturally occurring isotopes.Using the atomic masses on the periodic table,identify the pair in which the lighter isotope is the more abundant one.

Question

In both pairs of isotopes for sulfur and bromine, the lighter isotope is more abundant. For boron and vanadium, the heavier isotope is more abundant. For antimony, the difference in atomic mass between the two isotopes is much larger, so it is not a clear case of one being more abundant than the other.
