Question--Proper form for nuclear addition 1. The problem statement, all variables and given/known data Say I am doing Binding Energy calculations, and I want to know the sum of mass for all the parts for, say, Carbon12 (C12). Which of the following is the correct form: 2. Relevant equations 1.) 6p + 6n = total 2.) 6(H1) + 6n = total 3.) 6(H2) = total 3. The attempt at a solution I am betting on #2. For #1, it seems to me that neglecting electrons could change the result in huge atoms. In #3 the measured mass of H2 is NOT the same as H1 + n, because H2 has already lost mass in fusion. OK, I'm assuming #2 was the winner, would the following be accurate: total mass of parts for Pt78 = 78(H1) + 78n or total mass of parts for Bx = x(H1) + x(n) How'd I do?
