In Lecture 13 at 39 minutes, what is the Professor talking about when he says that they bombard silicon atoms with neutrons to make phosphorus because it changes the z-number? There are so many things wrong with that. You would make a new isotope but it would still be silicon. Additionally, the z-number is the number of protons, and has nothing to do with how many neutrons you add.

    Ahhh I'm thinking that the silicon must undergo beta decay afterwords and the professor skipped this point.
