Comparing the Size of the Hydrogen Atom’s Nucleus to its Orbital

Atomnucleusorbitals This exercise will assist students in visualizing how little of the space occupied by an atom actually contains matter.  This exercise will create a scaled model of the hydrogen atom with which students can zoom from an external view of the s-orbital down to the nucleus.  It should be noted that SolidWorks does not use measurements that accommodate the dimensions of an atom.  (The s-orbital diameter of a hydrogen atom is on the order of   10-10meters and the proton which forms the nucleus has a diameter on the order of 10-15meters.)

However if assigned units are ignored, the breadth of magnitudes in measurement that SolidWorks does provide will allow a scaled model of the atom to be viewed.  Contributed by Bruce Hamren.
