I have questions regarding nuclear fusion: 1: Can all atoms fuse, say a hydrogen and carbon atom, could they fuse? or does it need to be the same type of atoms. 2: Are there any equations that determine the force needed to fuse? I'd think it'd have to do with x and x2 number of protons meet, where the distance where the strong force overtakes the EM force is y, so the force required is equal or more than (x2*x1/y)k, but ofcourse structures in the nucleous and the electrons would complicate this.. 3: Are there any correlations to the stability islands, such as low energy fusions. Whereas some forms of fusions are lower energy, even if the number of protons is higher? I'd assume some atomic structures would allow for easier fusion.
