The light of halogen lamps is slightly more “whiteish” than incandescent lamps.
The halogen compounds of mercury, we should have mentioned, also sublime, the red iodide giving a yellow sublimate.
It is decomposed by the halogen elements and also by sulphuretted hydrogen.
halogen, hal′o-jen, n. a substance which by combination with a metal forms a saline compound.
halogens do not act directly on water, hence we may not properly speak of halogen substitution products.
Compounds containing oxides and fluorides, &c., do not lend themselves to the method of determining the halogen by difference.
The same as Method 1, except that after ignition of the saponified mixture the halogen was determined by weighing as silver iodid.
halogen acids convert it into monohalogen fatty acids, and the halogens themselves convert it into dihalogen fatty acids.
It combines with the halogen elements with great energy, burning brilliantly in chlorine to form antimony trichloride (SbCl3).
The products in question have the characteristics of solid solutions of the halogen.
general name for elements of the chlorine family, 1842, from Swedish, coined by Swedish chemist Baron Jöns Jakob Berzelius (1779-1848), literally "salt-producer," from Greek hals "salt" (see halo-) + -gen "giving birth to" (see -gen); so called because a salt is formed in reactions involving these four elements.
halogen hal·o·gen (hāl'ə-jən)
Any of a group of five chemically related nonmetallic elements including fluorine, chlorine, bromine, iodine, and astatine.
Any of a group of five nonmetallic elements with similar properties. The halogens are fluorine, chlorine, bromine, iodine, and astatine. Because they are missing an electron from their outermost shell, they react readily with most metals to form salts. See Periodic Table.
