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:
“By what a delicate and far-stretched contribution every island is made! What an enterprise of nature thus to lay the foundations of and to build up the future continent, of golden and silver sands and the ruins of forests, with ant-like industry.”
—Henry David Thoreau (1817–1862)
