The Element Of Surprise: Bismuth Edition

The perfect chemistry pun doesn't exi— Oh wait, here it is! This meme brilliantly plays on the dual meaning of "Bi" - both the element Bismuth (atomic number 83) and bisexuality. Bismuth really does form those gorgeous cubic crystal structures that oxidize into rainbow-colored surfaces. And yes, it's technically radioactive with a half-life of about 2×10^19 years (the universe is a mere baby at 13.8 billion years in comparison). The "pentavalent" reference? That's because Bismuth has 5 electrons in its outer shell available for bonding. Chemistry nerds unite - this is what happens when you combine periodic table facts with identity humor!
