What would need to happen in order to make a compound with neon and helium? We know it's impossible, but super hypothetically if we could do magic and fuse them together, how would that look like? Would a determined number of electrons have to go away? Would the van der Waals forces need to be weaker?
I'm trying to find visual ideas for a romantic fusion of two entities: Neon and Helium. I want to get as close to reality as possible (a molecule, not an atom). Since it isn't an actual possibility, I want to just to see if can get inspired with whatever gets the closest and get a sci-fi visual idea. Something that comes to mind is having them both be squeezed by two diamonds. I would appreciate getting better answers, even if they are sci-fi impossibilities.
