What is atomic radius of copper?

The atomic radius of copper is 128 pm (picometers) or 1.28 angstroms. This value is determined by measuring the distance between the nucleus of a copper atom and its outermost electron shell. Copper is a transition metal and has 29 electrons and 29 protons in its atomic structure. It is known for its excellent electrical conductivity and is commonly used in wiring, plumbing, and electronics. The atomic radius of copper is influenced by its electron configuration and nuclear charge, among other factors.
