Nickel with an average atomic mass of 58.65 amu has three isotopes. In the
lighter isotope, the difference in the
number of particles inside the nucleus
with each other is 2. The mass difference
between the other two isotopes is the size
of a neutron. The frequency of the heavier
isotope is 0.2% of the frequency of the
medium-mass isotope, and the difference
between neutrons and electrons is 7 in the
heavier isotope of nickel ion +2. What is
the percentage of lighter isotope
abundance?
