Why did the electron leave the atom?
Because it had its ion someone else.
Listen up, you silly goose! The joke is a pun. An electron is a tiny part of an atom, right? But "ion" sounds like "eyeing," which means looking at someone you like. So, the electron left because it was crushing on someone else. Get it? It's like a nerdy love triangle but with science words! You probably think water is dry.
