Etymology
Description
Halogen is an element. It is red in color and is a volatile liquid at room temperature. Its reactivity is between chlorine and iodine. It is harmful to human tissue in liquid form, and irritates the eyes and throat in gaseous form. It was discovered by Antoine Balard in 1823.
Language Of Origin
Greek via French
Origin Of Word
From the Greek word bromos meaning "bad smell"
Meaning
dirt, bad smell
Symbol Origin
Greek bromos
Etymological Description
Brómos means "stink" (literal meaning: clatter) because of its smell.
