Bromine

Bromine is the only non-metallic element that exists as a liquid at room temperature and pressure. This reddish-brown liquid has a strong, unpleasant odor – “bromine” comes from the Greek word “bromos,” meaning stench.

Bromine is used in flame retardants, pharmaceuticals, and even in purifying water. In 2014, researchers found that bromine is crucial for tissue development in all animals, from primitive sea creatures to humans. However in its liquid state bromine is corrosive to human tissue and can be highly toxic when inhaled as a vapor.
