The Flamboyant Element 83

Periodic table personalities on full display here. While most metals maintain a professional gray aesthetic (looking at you, tungsten), bismuth is that one colleague who shows up to the lab in rainbow socks and a tie-dye lab coat. Its crystalline structure creates an oxide layer that refracts light into a spectrum of colors, essentially turning it into the metal equivalent of that house with synchronized Christmas lights. Meanwhile, copper and gold are just basic elements with a single-tone personality. They're like the coworkers who think wearing a colored tie counts as "dressing up." Bismuth is literally showing the entire visible spectrum while they're stuck in monochrome. Element 83 didn't come to play—it came to slay the crystallography game.
