ELI5: What's the difference between a muonic atom and an electronic atom?
gpt
Muons are particals that function like electrons, but where electrons ha e almost immeasurably small mass, muons have a bigger mass that is clearly measurable. It's still a stupid small number though and really hard to write.

Anyway, a muonic atom has muons where one or more of it's electrons should be, so it winds up heavier overall.

They're pretty rare though.
