I am looking for a person knowledgeable in the structure of atoms; specifically the breakdown of radon and each element it breaks down into, and from. The number of protons, neutrons and electrons. I have an email I would like to send to someone who can help me. I perform radon testing and am making a coloring/storybook and that has led me to this. Thank you.
