Copper and its compounds have many important uses in modern society. Most electrical equipment has copper wiring. In fact, people often refer to anything with a reddish-brown tint as being copper colored. Copper metal is fairly soft and ductile. Ductile means capable of being drawn into wires. Copper is mined

This section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of copper. For each compound, a formal oxidation number for copper is given, but the usefulness of this number is limited for p -block elements in particular.
Discovery and naming The oldest objects made of copper are beads found in northern Iraq, which date to about 9000 B.C. Tools for working with copper, made in about 5000 B.C.,have also been found.In the New World, Native Americans used copper objects as early as 2000 B.C. The symbol for copper, Cu, comes from the Latin word cuprum.
2021-3-22 · Copper can be easily drawn into wires, and is the preferred electrical conductor for most wiring applications--roughly half of all copper mined is used in this way. In addition to being highly conductive, copper has high tensile strength, low thermal expansion, and resists corrosion and creep, properties which together result in reliable circuitry.
2020-6-17 · Copper compounds. Although copper is fairly unreactive, it can make a wide range of useful compounds (when copper atoms combine and bind chemically to atoms of other elements) and alloys (when copper atoms mix with atoms of metals and other substances). When it joins with other atoms, copper behaves chemically in two quite different ways to
Copper is one of the basic chemical elements. In its nearly pure state, copper is a reddish-orange metal known for its high thermal and electrical conductivity. There is evidence that by about 6400 B.C. copper was being melted and cast into objects in the area now known as Turkey. By 4500 B.C There are about 15 copper ores mined
