1a.) You have 16 electrons, 16 protons, and 16 neutrons. You can combine them to make 8 Helium (He-4) atoms, 4 beryllium atoms (Be-8), 2 oxygen atoms (O-16), or one sulfur atom (S-32). What will you do to make the most stable product?
Info:
H-1 1.00782505 amu
He-4 4.0026033 amu
Be-8 8.0053052 amu
O-16 15.9949146 amu
S-32 31.972072 amu
(I want to say its sulfur because it weighs more but i'm not sure)
b.) calculate the energy released in the fission reaction
Be-8 ------ 2 He-4
( I got -1.28x10^(-6) MeV/Be) but i don't think i did it correctly)

2.) the molecule benzene has a molecular formula C6H6. If the relative abundance of Carbon-13 is 1% of that for carbon-12, what can be said about the ratio of the two parent ions corresponding to masses of 78 and 79 amu
