(Ag) Metal |

Pure
silver is nearly white, lustrous, soft, very ductile, malleable, it is an
excellent conductor of heat and electricity. It is not a chemically active
metal, but it is attacked by nitric acid (forming the nitrate) and by hot
concentrated sulfuric acid. It has the highest electrical conductivity of
all metals, but its greater cost has prevented it from being widely used
for electrical purposes.
Silver
is almost always monovalent in its compounds, but an oxide, a fluoride,
and a sulfide of divalent silver are known. It does not oxidize in air but
reacts with the hydrogen sulfide present in the air, forming silver
sulfide (tarnish). This is why silver objects need regular cleaning.
Silver is stable in water.
