Lol nice, but there is an easier way to explain it all. Fission means the splitting of an atom (Ernest Rutherford 4 Life!), and Fusion means to merge or join atoms. Having two hydrogen atoms gives you H2 (with 2 being the number down there...).
Binary Fission is something I learned today, literally meaning "2 Splitting". Splitting in two. Hope I helped as well to the cause.
(BTW- I'm Poorsoft)
Might as well talk about what makes the molecules unstable (The Electrostatic force being stronger than the strong nuclear force) and the so called 'Island of stability' and the 1:1 and 2:1 (for heavier elements) ratio of protons and neutrons.
You also forgot to mention positron decay, and the decay series of elements.
hope this helps!
