  2. Bromine (or ; from βρῶμος, brómos, meaning "stench (of he-goats)"), is a chemical element with the symbol Br and atomic number 35. It is in the halogen element group. Bromine vapors are corrosive and toxic. Approximately 556,000 metric tons were produced in 2007. ...
  3. A nonmetallic chemical element (symbol Br) with an atomic number of 35; one of the halogens; A bromine atom in a molecule
  4. A common name for a chemical compound containing bromine that is used as a disinfectant to destroy bacteria and algae in swimming pools and spas. Available as a tablet or as sodium bromide, a granular salt.
  5. Symbol:"Br" Atomic Number:"35" Atomic Mass: 79.90amu. Bromine is a member of the halogen group. Bromine is the only non-metallic element that is a liquid at room temperature. ...
  6. A brownish-red element that is a liquid at room temperature, dissolves in water, and has a bleach-like suffocating odor. Bromine occurs naturally in the earth's crust and seawater. Bromine is found as an alternative to chlorine in swimming pools. ...
  7. A chemical element, normally a deep-red liquid, which fumes readily and mixes easily with water. Used as a water disinfectant in combination with chlorine as bromine chloride.
  8. Chemical sanitizer that kills bacteria and algae.
  9. Oxidizing agent used for sanitizing spa water. Not as aggressive as chlorine.
  10. A halogen disinfectant. Cannot be stabilized against ultraviolet light. It is the optimum sanitizer for spas and indoor pool settings.
  11. This halogen is usually used as a spa sanitizer.
  12. a sanitizer similar to chlorine, commonly used in spas.  Very effective against bacteria, but it cannot be stabilized, so it is susceptible to deterioration by sunlight.  When it combines with ammonia compounds, it is still an effective sanitizer, unlike chlorine.
  13. A fire retardant (halogen) which is used to reduce or eliminate a resin's tendency to burn. Often used in conjunction with chemicals such as antimony trioxide and pentoxide to achieve a maximum Class 1 fire retardancy rating and often used in ducting systems.
  14. A halogen sanitizer (in the same chemical family as chlorine) designed to kill bacteria and algae in the spa. Bromine is commonly used in stick, tablet or granular form.
  15. B-R. For more information on this and other elements, see The elements. And for fun, see Elements by Tom Lehrer. To see this song with captions, go to The Elements song by Tom Lehrer.

  17. A halogen element; alternative sanitizer for pools. Most effective in spas and indoor pools.
  18. a chemical product used to sanitize pools or spas.
  19. The preferred sanitizing agent for hot tub spas that kills bacteria and algae. The tablet form of this product is dispensed using a floating brominator. The granular form is added upon spa startup (initial filling) to establish an immediate bromine reserve. ...
  20. a halogen element used in place of chlorine as a sanitizer in swimming pools and spas.
  21. Bromine is the only liquid nonmetallic element. It is a heavy, volatile, mobile, dangerous reddish-brown liquid. The red vapor has a strong unpleasant odor and the vapor irritates the eyes and throat. It causes severe burns upon contact with the skin. ...
  22. A member of the halogen family, commonly used as a sanitizer in spas, because it is effective in a wide range of water temperatures and pH levels. Less commonly used for pools, bromine is both an oxidant and a biocidal agent.
