That's not a wish, that's a recipe for universal annihilation. Adding an extra electron to every atom would catastrophically destabilize electron shells, trigger spontaneous nuclear reactions, and basically turn the entire universe into one giant unstable mess.

Congratulations on finding the most efficient way to end existence without technically asking for it directly. Chemistry departments should put this on their "forbidden wishes" list.
