If you did manage to do this by random chance would you even notice? A single atom is pretty small. If you somehow split a random carbon atom in lettuce wouldn't you get less than a Joule as long as it doesn't somehow chain?

This is just what I've heard a long time ago so don't quote me lol. But no, splitting a single atom shouldn't do anything of note. I believe it's the same general reason that a nuke doesn't set the entire atmosphere on fire - you need a lot of energy to split atoms. That's why nukes need enriched materials.

I also believe that even a nuclear explosion won't be triggered by a single split atom in a bomb. For example, the Manhattan Project bomb was triggered by shaped explosives that surrounded the nuclear core. The blast of the charges "compressed" the nuclear material to the point it reached a critical mass that allowed a runaway fission reaction.

Yeah it would be small to the point of not being perceptible. A single atom has an insane amount of energy for its size, but its still not enough to move a grain of sand any amount that would be perceptible to the naked eye
