Voorbeelden van het gebruik van HALOGEN in een zin

• A halogen lamp (also called tungsten halogen, quartz-halogen, and quartz iodine lamp) is an incandescent lamp consisting of a tungsten filament sealed in a compact transparent envelope that is filled with a mixture of an inert gas and a small amount of a halogen, such as iodine or bromine.
• The chief differences from pyroxenes are that (i) amphiboles contain essential hydroxyl (OH) or halogen (F, Cl) and (ii) the basic structure is a double chain of tetrahedra (as opposed to the single chain structure of pyroxene).
• The haloalkanes (also known as halogenoalkanes or alkyl halides) are alkanes containing one or more halogen substituents.
• In 2022, folksinger Willi Carlisle created an album titled Peculiar, Missouri; referencing the town of Peculiar, with one song mentioning a local Walmart and its "hideous halogen bulbs" in the general area of the same name.
• The elements in period 2 often have the most extreme properties in their respective groups; for example, fluorine is the most reactive halogen, neon is the most inert noble gas, and lithium is the least reactive alkali metal.
• In chemistry, a halide (rarely halogenide) is a binary chemical compound, of which one part is a halogen atom and the other part is an element or radical that is less electronegative (or more electropositive) than the halogen, to make a fluoride, chloride, bromide, iodide, astatide, or theoretically tennesside compound.
• As it attacks and forms a bond with one of the carbons, the bond between the first bromine atom and the other carbon atoms breaks, leaving each carbon atom with a halogen substituent.
• It is produced by the reaction of ethylene gas with bromine, in a classic halogen addition reaction:.
• Though cheaper, the acetate filters eventually fell out of favor with professional organizations since they could not withstand the higher temperatures produced by the tungsten halogen lamps that came into widespread use in the late 1960s.
• In addition to dioxygen, oxidants can include halogen compounds, ozone, hydrogen peroxide, and oxides of nitrogen.
• Cyanogen molecules consist of two CN groups ‒ analogous to diatomic halogen molecules, such as Cl, but far less oxidizing.
• Early in the model year, the headlight was changed to a non-sealed beam unit with a replaceable halogen bulb.
• Although variable-voltage devices are used for various purposes, the term dimmer is generally reserved for those intended to control light output from resistive incandescent, halogen, and (more recently) compact fluorescent lamps (CFLs) and light-emitting diodes (LEDs).
• FR-4 epoxy resin systems typically employ bromine, a halogen, to facilitate flame-resistant properties in FR-4 glass epoxy laminates.
• Several pathways exist for the halogenation of organic compounds, including free radical halogenation, ketone halogenation, electrophilic halogenation, and halogen addition reaction.
• He then went on to study alkali halides in the gas phase, first at the University of Michigan and then at Yale, using shock waves to produce sufficient dissociation of the molecules to ions to make it feasible to observe the photodetachment spectra of the halide ions, thus determining the electron affinities of the halogen atoms to four or five significant figures.
• Shirakawa found that, when a trace of a halogen such as bromine or iodine is added to thin film polyacetylene, its electric conductivity increases, and it exhibits metallic conductivity.
• The list offered Open Road Handling Package, Two-Tone Paint, interior lighting, air conditioning with an upgraded climate control feature, rear window defroster, cruise control, power adjustable front seat, power windows, power electric door locks, power trunk release, luxury appearance steering wheel with an extra cost leather wrapped feature, digital clock, locking gas cap, lighting and mirrors, halogen headlamps, cornering lamps, electric adjustable outside sideview mirrors, several AM/FM radio or separate stereo radio choices to include CB and 8-track cassette player, power electric extendable antenna, various vinyl side moldings and bumper guards, undercoating, color keyed seat belts, wheel covers, and aluminum wheels, all at extra cost.
• From September 1969 the rectangular headlights were replaced with twin halogen units, and air extractor vents appeared on the C-pillar behind the doors.
