A silver halide is one of the compounds formed between silver and one of the halogens — silver bromide (AgBr), chloride (AgCl), iodide (AgI), and three forms of silver fluorides. As a group, they are often referred to as the silver halides, and are often given the pseudo-chemical notation AgX. Although most silver halides involve silver atoms with oxidation states of +1 (Ag+), silver halides in which the silver atoms have oxidation states of +2 (Ag2+) are known, of which silver(II) fluoride is the only known stable one.
The light-sensitive chemicals used in photographic film and paper are silver halides.
Famous quotes containing the word silver:
“Or ever the silver cord be loosed, or the golden bowl be broken, or
the pitcher be broken at the fountain, or the wheel broken at the
cistern.
Then shall the dust return to the earth as it was: and the spirit
shall return unto God who gave it.
Vanity of vanities, saith the preacher, all is vanity.”
—Bible: Hebrew Ecclesiastes (l. XII, 6–7)
