If you wanted to make an accurate scale model of the hydro- gen atom and decided that the nucleus would have a diameter of 1 mm, what would be the diameter of the entire model? I understand the answer however wouldnt the end result be much smaller than 106 mm since we are only find the diameter of the nucleus? Is the 106 always used in these types of equations? What would be used in this equation for say a carbon atom?

NucleonsThe term nucleon refers to the particles found in the nucleus of an atom, namely protons and neutrons. A single hydrogen atom (one proton plus one electron) has a mass of 1.007825 amu. A single neutron has a mass of 1.008665 amu. Note that amu stands for "atomic mass unit" and is sometimes abbreviated with the symbol uu. 1 uu is equivalent to 1.665387×10-27 kgPart A Calculate the mass defect of the fluorine nucleus 19-9F.
