Question

Bromine has an atomic mass of 79.9 amu, but only has 2 naturally occurring isotopes, Bromine-79 and Bromine-81. If Bromine-80 does not exist, what does that suggest about the relative abundances of Bromine-79 and Bromine-81? PLEASE HELP ME! 25 POINTSSSSS

Since Br-80 does not exist, maybe that means Br-79 or Br-81 have very unequal abundances. For example, Br-79 may have 75% abundance whereas Br-81 may have 25% abundance.
