Cl-chlorine-17

Fun facts: Chlorine is a highly reactive element known for keeping pools clean and drinking water safe. But as a strong respiratory irritant, it's also very dangerous, even fatal. A truly double-edged element. Great for: Swimmers, germaphobes, and anyone turning 17 (Chlorine's atomic number). Buy your friend a Sodium hat (Na), then go out and get salty together (NaCl, sodium chloride 😊). A refreshing gift for lifeguards and pool boys.
