The unsaturated benzene ring readily reacts with halogens, rapidly discoloring bromine water. |
|
It combines easily with many non-metals, including nitrogen, sulfur, phosphorus, and the halogens. |
|
For many syntheses, this means using such compounds as hydrocarbons and alcohols, plus inorganic acids, metals, halogens, or other compounds. |
|
Graham was installing under-cupboard halogens to replace the over-bright fluorescent tube we inherited from the previous owners. |
|
Common oxidants include the halogens, oxygen, ozone, potassium permanganate, potassium dichromate, nitric acid, and concentrated sulfuric acid. |
|
The lower pull-down menu lets you mark groups of elements, such as the halogens or the alkaline earth metals, on the plot. |
|
Four important chemical family names of elements still widely used are the alkali metals, the alkaline earths, the halogens, and the noble gases. |
|
At higher temperatures, the metal does combine with many acids, the halogens, sulfur, selenium, and tellurium. |
|
The halogens are a group of chemical elements that includes fluorine, chlorine, bromine, iodine, and astatine. |
|
Use hydrogen and halogens as terminal atoms and then use the least electronegative atom as the central atom. |
|
Barium is an active metal that combines easily with oxygen, the halogens, and other non-metals. |
|
Because halogens are highly electronegative, their atoms normally retain negative charge in these compounds. |
|
Metals high on the activity series react more vigorously with oxidants including the halogens and the hydronium ion than those lower on the scale. |
|
Another stylish feature is the « ciel etoile » effect and the underwater halogens. |
|
Bonding to carbon the halogens form a class of compounds called covalent halides, i.e. they are not electroylytic in nature. |
|
Recent experiments have begun identifying oxidizing gases, such as ozone and molecules containing the halogens bromine and chlorine, as triggers for that mercury fallout. |
|
Silicon behaves somewhat similarly to carbon, but compounds of silicon and hydrogen or silicon and the halogens are much more reactive than their carbon counterparts. |
|
I ventured solo toward the lodge for a brief ride through a nice eight inches of powder away from the over-bright halogens into the darkened trees. |
|
Several halogens including chlorine, fluorine and iodine, have important applications in everyday life. |
|
How does the order of the halogens in Group 7 compare with the reactivity of these halogens? |
|
|
Gases that are most damaging to stratospheric ozone contain the chemicals chlorine and bromine, called halogens, and various source gases transport both into the stratosphere. |
|
It is not uncommon to rely, as well, on zinc borate which can synergistically react with antimony oxide as well with halogens. |
|
The metal reacts with the halogens, giving rise to compounds with the general formula PuX3 where X can be F, Cl, Br or I and PuF4 is also seen. |
|
The highly electronegative fluorine substituent stabilizes this intermediate much more than do the other halogens and causes it to be formed faster. |
|
Disinfectants successfully used in private swimming pool include halogens, usually chlorine and bromide, which not only kill off germs, but also react with and oxidise other contaminating organic materials. |
|
Next in the series of energy efficiency improvements is a lighting retrofit, which will replace existing halogens and install remote sensors to control lighting. |
|
Among the halogens only fluorine reacts with elemental carbon. |
|
Iron forms binary compounds with the halogens and the chalcogens. |
|
Unlike copper, silver will not react with the halogens, with the exception of the notoriously reactive fluorine gas, with which it forms the difluoride. |
|
It reacts with carbon, halogens, nitrogen, silicon and hydrogen. |
|
Elemental halogens have seven valence electrons and are very reactive. |
|
Halogens are still the light of choice where such effects are desired in a gallery area. |
