one of the family of chemical elements including fluorine, chlorine, bromine and iodine
the name given to the group of elements having seven valence electrons; any member of the nonmetallic elements in Group 7A of the periodic table.
The group of elements comprising chlorine, bromine, iodine and fluorine. Of these, chlorine and bromine are used to sanities pool and spa waters.
Fluorine, chlorine, bromine, iodine and astative. Usually diatomic molecules and toxic.
nonmetallic elements including fluorine, chlorine, bromine, iodine and astatine
a family of chemical elements that includes fluorine, chlorine, bromine, and iodine
(See QUARTZ HALOGEN LAMP)
One of the chlorine group (bromine, chlorine, fluorine, iodine) of elements, all univalent; they form monobasic acids with hydrogen, and their hydroxides (fluorine forms none) are monobasic acids. The radioactive element, astatine, also belongs to the halogen group.
Fluorine, chlorine, bromine, iodine and astatine are all halogen elements.
Any one of the four chemical elements; chlorine, fluorine, bromine or iodine.
A family of chemical elements containing Chlorine, Bromide, Fluorine, Iodine, and Astatine. With the exception of Astatine, the Halogen family is widely used for a variety of sanitizing situations.
any of five related nonmetallic elements (fluorine or chlorine or bromine or iodine or astatine) that are all monovalent and readily form negative ions
Any one of the five elements in Group VII of the Periodic Table, i.e. Fluorine, Chlorine, Bromine, Iodine or Astatine. Ion : An atom or molecule that has become electrically charged, either by gaining electrons (in the case of a negative ion) or by losing them (in the case of a positive ion).
Refers to any of five chemical elements-astatine (At), bromine (Br), chlorine (Cl), fluorine (F), and iodine (I)- that may be found in some refrigerants.
A type of incandescent light that uses metal halides in compact, highly efficient bulbs, tubes, and reflectors.
A light emitting true color characteristics. Fluorescent and other lights tend to give a room a yellowish or greenish cast; halogen light remains neutral. A halogen lamp’s small bulbs are energy-efficient and long lasting.
A non-metallic element, such as fluorine, chlorine, bromine, iodine, or astatine.
A term, whose literal meaning is “saltmaker”; refers to the five elements of Group VIIA of the Periodic Table—fluorine, chlorine, bromine, iodine and astatine.
Small, hot-burning bulbs, often used for task or accent lighting. Halogen bulbs have a longer life and provide more light per watt.
See Tungsten Halooen Lamp.
The group VIIa elements in the periodic table.
An incandescent lamp containing halogen gas which recycles the tungsten.
any of the elements flowering, chlorine, bromine, iodine and astatine existing in a free state: Halogens are in the arc tube of a halide lamp
Elements that attack carbon. Fluorine, bromine, chlorine, astatine and iodine.
Incandescent bulb filled with halogen gas to increase the intensity of the light and increase the life of the bulb
Gas contained in the lamp of a quartz light.
Any of five nonmetallic chemical elements: fluorine, chlorine, bromine, astatine and iodine. Chlorine is used as a bleach and disinfectant. Bromine is used in dyes and for flame-proofing. The Fluorocarbon form of fluorine is used as a lubricant, refrigerant and in fire extinguishers.
Halogen bulbs are used in most low- and medium-priced projectors. They last about 40 hours.
A halogen, from the Greek words Halo ( "salt") and Gen ("creator"), is any of the 5 chemical elements in Group 17 of the periodic table of the elements. These elements are fluorine, chlorine, bromine, iodine, and astatine. Iodine and bromine gas are commonly used inside halogen light bulbs to extend the life of the lamp.
Any member of the group of chemically related nonmetallic elements which include fluorine, chlorine, bromine, and iodine.
A type of incandescent light bulb that is filled with halogen gas. They are smaller and brighter than regular light bulbs. The light is "white", so things look the color they really are. It's a good choice for putting makeup on by.
A special type of lamp known for its quality of brilliant white light. Originally used for fog lights and driving lights.
See Tungsten Halogen Lamp.
A member of the family of elements fluorine, bromine, chlorine and iodine.
Halogen light bulbs are high pressure tungsten filament lamps containing halogen gases. The halogen gases allow the filaments to operate at higher efficacy than incandescent lamps. Halogen lamps also provide brighter, whiter light with better color characteristics, longer service life and improved energy efficiency.
group VIIA; group 18. An element of group VIIA (a. k. a. Group 18). The name means "salt former"; halogens react with metals to form binary ionic compounds. Fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At) are known at this time.
A light that emits true color characteristics, unlike fluorescent and other lighting that tend to give a room a yellowish cast, halogen's light remains neutral.
Any of a group of five chemically related nonmetallic elements that includes bromine, fluorine, chlorine, iodine, and astatine.
any of the electronegative elements; fluorine, chlorine, iodine, bromine, and astatine; that form binary salts by direct union with metals
Any one of these five elements: fluorine, chlorine, bromine, iodine, and astatine.
Non-metallic elements fluorine, chlorine, bromine & iodine.
A type of incandescent lamp with higher energy-efficiency that standard ones.
A term used to identify any of the four elements: chlorine, fluoride, bromide and iodine, grouped together because their chemical properties are similar.
Incandescent light source which uses compact, highly efficient bulbs. Special fixtures are required for their use.
The halogens are a chemical series of nonmetals. They are the elements in Group 17 (old-style: VII or VIIA; Group 7 IUPAC Style) of the periodic table: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At) and as yet undiscovered ununseptium (Uus). The term halogen was coined to mean elements which produce a salt in union with a metal.
