**Bromium** (uut Griechisk βρωμος (brómos), wät 'Stoank' hat) is n chemisk Element in ju periodiske Tabelle mäd Symbol **Br** un Atomtaal 35. Bromium is n Halogen , die der rood fon Faawe is un die der bie Ruumtemperatuur ne fluchtige Flüssegaid is, ju der mäkkelk reagiert mäd Chlor un Iod. Dät Element is as Flüssegaid korrosiv foar dät moanskelke Geweeuwe un die Damp raitset do Oogene un ju Kääle. Broomdampe sunt gjucht giftich, wan do ienommed wäide.
