What element has the symbol 'Br'?

The story behind the answer

Br is the symbol for Bromine, a halogen in Group 17. The similar-looking options have different symbols: Barium is Ba, Bismuth is Bi, and Boron is B.

Bromine is a distinctive reddish-brown liquid at room temperature—the only liquid nonmetal—and its name comes from the Greek “bromos,” meaning stench, due to its strong, irritating odor. Bromine compounds have been used in flame retardants and photographic films (e.g., silver bromide). Memory tip: “BRown, BRiny BRomine”—it’s brownish and was first isolated from salt brines; or “BRomine smells BRutal” to link Br to its pungent odor.
