What are the Properties of Copper? What is the definition of Copper? It is a ductile, malleable, reddish-brown metallic element that is an excellent conductor of heat and electricity and is widely used for electrical wiring, water piping, and corrosion-resistant parts, either pure or in alloys such as brass and bronze. The Physical and Chemical Properties are the characteristics of a substance, like Copper, which distinguishes it from any other substance. Most common substances, like Copper, exist as States of Matter as solids, liquids, gases and plasma. Refer to our article on Copper Element for additional information and facts about this metallic substance.
Allotropes Some elements exist in several different structural forms, called allotropes. Each allotrope has different physical properties. For more information on the Visual Elements image see the Uses and properties section below. Group A vertical column in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell.
Copper was one of the earliest elements known to man. At one time, it could be found lying on the ground in its native state or uncombined state. Copper's distinctive red color made it easy to identify. Early humans used copper for many purposes, including jewelry, tools, and weapons. Copper is a transition metal, one of several elements found in rows 4 through 7 between Groups 2 and 13 in the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. Copper and its compounds have many important uses in modern society.
Copper is a well-known element because of its distinctive reddish metallic color and because it occurs in pure form in daily life. Here is a collection of facts about this beautiful transition metal:. Atomic Number: The atomic number for copper is 29, which means every copper atom contains 29 protons. Symbol: Cu from Latin: cuprum. Atomic Weight : Discovery: Copper has been known since prehistoric time.
Copper is the oldest metal used by man. Copper has been mined for more than 10, years with a Copper pendant found in current day Iraq being dated to BC. Copper is found as native metal and in minerals cuprite, malachite, azurite, chalcopyrite and bornite. It is also often a by-product of silver production. Sulphides, oxides and carbonates are the most important ores.
It delivers electricity and clean water into our homes and cities and makes an important contribution to sustainable development. More than that, it is essential for life itself. The following describes different properties of copper, divided by type chemical, mechanical and physical. All common metals and alloys react with a moist atmosphere and corrode. However, due to the chemical properties of copper, the corrosion process is very slow.
Copper is a reddish metal with a face-centered cubic crystalline structure. It reflects red and orange light and absorbs other frequencies in the visible spectrum, due to its band structure, so it as a nice reddish color. It is malleable, ductile, and an extremely good conductor of both heat and electricity. It is softer than zinc and can be polished to a bright finish. It is found in group Ib of the periodic table , together with silver and gold.
