refer to the peridodic table. why are the average atomic mass of H thru Bi generally not whole numbers? why are Pu thru Und whole numbers? this is a good analogy of the relative abundances of different isotopes of the same element. what is wrong with this analogy? think about the isotopes used here and how they are different in from the isotopes of elements found in nature. .

1. refer to the peridodic table. why are the average atomic mass of
H thru Bi generally not whole numbers? why are Pu thru Und
whole numbers?
this is a good analogy of the relative abundances of different
isotopes of the same element. what is wrong with this analogy?
think about the isotopes used here and how they are different in
from the isotopes of elements found in nature.
