The molecular mass for chlorine is not an integer multiple of the molecular mass of hydrogen but is about 35.5 times the molecular mass of hydrogen. This is primarily because:
a. of the binding energy of the chlorine nucleus.
b. there are different isotopes of chlorine.
c. the chlorine nucleus has 35.5 nucleons.
d. the proton and neutron have different masses.
Question 2
For every stable nucleus except hydrogen, if the number of nucleons is doubled, the quantity that will change least is the:
a. density.
c. charge.
b. mass.
d. volume.
