we're going to funds a number off Yushin Seen these animals p u. Before we do that, that's just over this top number. Prickly. So what does this represent? Two or 39? What's that? Yes, that's the mass hunger. And what ISS last number Read a case number off pro Tom's class number off New Shin's often out of your element. Right. So now we have Samast number and we need to find a number of U turns. So what we need right now is number of cold hands off this p U. So that's, um, go to the periodic table and found out what to you is reds. We could sit. The anti atomic number is 94 so P U stands for cotillion. Joe Tonio French. So using this equation to 39 because to number of protons, which is the economic number with red here it's the last 94 place number off nuisance. So by during a single subtraction, number of fusion's is equal to 2 39 minutes 94 which is 1 45 That's the number of New Shins were looking for
