3) A neutron source is surrounded by a 1 cm thick spherical shell that
has an atomic number density of 1024 atoms/cm3. What is the minimum microscopic cross-section (in barns) required to attenuate 99.99% of the neutrons?
4) how many moles of copper can they produce from 1.87 grams of aluminum reacts with 9.65 grams of copper (II) sulfate
5) Describe what an isotope is and explain how it relates to the masses
you see for each element on the periodic table. ( why are the masses decimals instead of whole numbers). What is the difference between an isotope and a ion.
