Meet the Chemiballs: Halogen Shenanigans
“Halogen” is a collective name for the elements that fall under fluorine in the periodic table. They all have the naming convention of ending in “-ine”, so you always know when something is a halogen. Though the same naming convention is used for a lot of random chemicals, like cadaverine or quinine, so it’s not a perfect system.
They're pretty scary chemicalballs 'cause they really like electronballs. Like, they really heckin' like 'em. They'll sell your own mother just to get a sweet sweet taste of that electronegativity.
POV you are being mugged by Flourineball. Hand over your electrons.
Astatineball is horrified as Tennessineball fades away after giving its final message. Astatineball knows it has a 50% chance of being doomed to the same fate in 8.1 hours or so (both elements have very short half-lives)
