Textbook Question
Chapter 17, Problem 20E
Look at the chemical elements in Appendix K. Can you identify any relationship between the abundance of an element and its atomic weight? Are there any obvious exceptions to this relationship?

The Theta nuc solution is incorrect.
"Determine the angle between the momentum of the electron and the momentum of the second (recoiling) nucleus." Please rework it as it cannot be 125 degrees. (A tad frustrating I have to spend another of my limited 30 questions on this)
The hydrogen atom's nucleus is a proton (mass 1.7 x 1027 kg), outside of which there is a single electron (mass 9.1 x 10-31 kg) at an average separation distance (d) of 5.3 x 10-11 m. To solve for elecrtric force, use Coulomb's law, where electron charge q1 and the proton charge q2 have the same magnitude (1.6 x 10-19 C).
An aspiring physicist wants to build a scale model of a hydrogen atom for her science fair project. If the atom is 1.00 m in diameter, how big should she try to make the nucleus?
