4. Suppose a mlddle school class is bulding a simplifed model of a hydrogen atom. They ball with a 2-centimeter diameter for the nucleus. a. What is the scale of their model? Write a ratio of the model nucleus dlameter to the actual nucleus dlameter. Do not simplity the ratio. Diameter of an actual hydrogen nucleus 1.75 x 10 " m Answer: Model of Hydrogen Atom proton at the nucleus electron's orbit electron b. If the dlameter of the hydrogen atom is 23,000 times larger than the diameter of the nucleus, find the diameter Ironen atom in the scale model in centimeters.
