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:
““Maman”, said Annaïse, her voice strangely weak. “Here is the water.”
A thin blade of silver came forward in the plain and the peasants ran alongside it, crying and singing.
...
“Oh, Manuel, Manuel, why are you dead?” moaned Délira.
“No”, said Annaïse, and she smiled through her tears, “no, he is not dead”.
She took the old woman’s hand and pressed gently against her belly where new life stirred.”
—Jacques Roumain (1907–1945)
