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:
“His golden locks time hath to silver turned;
O time too swift, O swiftness never ceasing!
His youth ‘gainst time and age hath ever spurned,
But spurned in vain; youth waneth by increasing.
Beauty, strength, youth are flowers but fading seen;
Duty, faith, love are roots, and ever green.”
—George Peele (1559–1596)
