Definition of bromine in English:

bromine

noun ˈbrəʊmiːnˈbroʊmin
mass noun
  • The chemical element of atomic number 35, a dark red fuming toxic liquid with a choking, irritating smell. It is a member of the halogen group and occurs chiefly in the form of salts in seawater and brines.

    Example sentencesExamples
    • ‘While chlorine and bromine chemicals cause the ozone hole, temperature is also a key factor in ozone loss,’ Newman said.
    • Other nations have signed since then, and recent studies indicate that the levels of bromine, another ozone-destroying chemical, are actually dropping.
    • The spa's thermal waters, which bubble out of the ground at 38 degrees centigrade, have a high incidence of sulphate sodium, bromine and iodine and are particularly beneficial for those with respiratory conditions.
    • The ozone depleting compounds contain combinations of the elements chlorine, fluorine, bromine, carbon and hydrogen.
    • The elements that appear enriched from measurements that Spirit took with her alpha particle x-ray spectrometer are potassium, phosphorous, sulfur, chlorine, bromine.
    • So, in the Lounge, we are reminded that computers, TVs, and radios contain such deadly things as cadmium, arsenic, bromine, and lead mercury.
    • Then there was chlorine, bromine, and iodine: pungent, poisonous, and coloured gases.
    • Jacob Berzelius immediately denominated chlorine, bromine, and iodine as ‘halogens’ or elements that form salts.
    • The proportion of bromine to other chemically similar elements, like chlorine, varied by a factor of 10 from place to place.

    • The two main ingredients are reactive halogen gases such as chlorine or bromine and sunlight.
    • Along with carbon, they include elements such as hydrogen, oxygen, fluorine, chlorine, bromine, sulphur or nitrogen.
    • Fluorine, chlorine, and bromine are all more chemically reactive than iodine; when in the body, they all tend to disrupt stable iodine molecules, displacing the iodine and causing its excretion.
    • Organohalogens are organic compounds that contain one or more halogen atoms (fluorine, chlorine, bromine or iodine).
    • While chlorine and bromine chemicals cause the ozone hole, extremely cold temperatures, especially near the edge of Antarctica, are also key factors in ozone loss.

    • The halogens are a group of chemical elements that includes fluorine, chlorine, bromine, iodine, and astatine.
    • Recent experiments have begun identifying oxidizing gases, such as ozone and molecules containing the halogens bromine and chlorine, as triggers for that mercury fallout.
    • For instance, electronegativities in the halide sequence fluorine, chlorine, bromine, and iodine decrease from fluorine through iodine.

Origin

Early 19th century: from French brome, from Greek brōmos 'a stink', + -ine4.
