Periodic table group
Group 11
Group 11 is a vertical column of the periodic table containing Copper, Silver, Gold, Roentgenium. Elements in the same group have the same number of valence electrons, which is why they show related chemical behavior. Copper, silver and gold are often called the coinage metals. They are the best electrical conductors of all the elements and are found in wiring, mirrors and jewelry.

Frequently asked questions
What elements are in group 11?
Group 11 contains 4 elements: Copper, Silver, Gold, Roentgenium.
What properties do group 11 elements share?
Elements in group 11 have the same number of valence electrons, so they react in related ways. Atomic radius increases down the group as electron shells are added, and first ionization energy generally decreases down the group. Copper, silver and gold are often called the coinage metals. They are the best electrical conductors of all the elements and are found in wiring, mirrors and jewelry.
Why are they called the coinage metals?
Copper, silver and gold are often called the coinage metals. They are the best electrical conductors of all the elements and are found in wiring, mirrors and jewelry.
