Silver is similar in its physical and chemical properties to its two vertical neighbours in group 11 of the periodic table: copper, and gold. Its 47 electrons are arranged in the configuration [Kr]4d 10 5s 1 , similarly to copper ([Ar]3d 10 4s 1 ) and gold ([Xe]4f 14 5d 10 6s 1 ); group 11 is one of the few groups in the d-block which has a ...

The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.
Group 11, by modern IUPAC numbering, [1] is a group of chemical elements in the periodic table, consisting of copper (Cu), silver (Ag), gold (Au), and roentgenium (Rg), although no chemical experiments have yet been carried out to confirm that roentgenium behaves like the heavier homologue to gold.
Silver salts have antiseptic properties. In 1881 Credé introduced a method known as Credé's prophylaxis , which used of dilute (2%) solutions of silver nitrate in newborn babies ' eyes at birth to prevent contraction of gonorrhea from the mother, which could cause blindness via ophthalmia neonatorum .

Naturally occurring silver (47 Ag) is composed of the two stable isotopes 107 Ag and 109 Ag in almost equal proportions, with 107 Ag being slightly more abundant (51.839% natural abundance). Notably, silver is the only element with all stable istopes having nuclear spins of 1/2.
