The atomic radius of copper is, and the ionic radius is. The distribution of copper in the earth's crust is.

The crystalline structure of solid copper is a face-centered cubic lattice with long edges. The density of solid copper is at 20 and 1083; The density of liquid copper is at 1083 and at 1600.

The viscosity of liquid copper is 1145.

The electrochemical equivalent of divalent copper ions is equal to gram ampere-hours.

Gases in the metal copper.

Liquid copper dissolves many common gases – hydrogen and sulphur dioxide.

Oxygen, nitrogen, carbon dioxide.

Carbon monoxide and water vapor. Solubility of the gas.

Determined by the situation in copper; The absorption of gases by Jinfeng is not only due to the dissolution of gases, but also the result of the chemical interaction between gases and metals and metals. The dissolved gases have an effect on the mechanical and electrical properties of copper: it deteriorates the quality of copper.

Therefore, in the production of refined copper, it is necessary to pay attention to eliminating the effect of gas dissolution in the final production port of copper smelting.

The chemical formula of copper is Cu. Copper (cuprum) is a metallic element.

Trepidation is also a transitional element.

Chemical symbol cu, English copper, atomic number.

Introduction

Copper is a non-ferrous metal that is very closely related to human beings, and is widely used in electrical, light industry, machinery manufacturing, construction industry, national defense industry and other fields, second only to aluminum in the consumption of non-ferrous metal materials in China.

Copper is a red metal as well as a green metal. It is said that it is a green metal, mainly because it has a low melting point, and it is easy to remelt and re-smelt, so it is quite cheap to use. In ancient times, it was mainly used for utensils, works of art and casting, and the more famous utensils and works of art such as the stepmother Wuding.

Copper is a heavy metal element that is not very reactive. It does not react with oxygen in dry air at room temperature. However, when heated, it can be oxidized to form black copper oxide CuO: if it continues to burn at a very high temperature, it will produce red cuprous oxide Cu2O, which is toxic.

Copper is a transition element, the chemical symbol Cu, English copper, atomic number 29.

1.Reaction with air (O2, H2O, CO2): After being left in humid air for a long time, a layer of patina (basic copper carbonate) will slowly form on the surface of copper, which prevents further corrosion of the metal, and its composition is variable.

2.Reaction with halogens: Copper can be combined with chlorine under ignition conditions.

3.Reaction with ferric chloride solution: In the electronics industry, FeCl3 solution is commonly used to etch copper to make printed lines.

4.Reaction with air and dilute acids: In the potentiometric order (metal activity order), the copper group elements are all after hydrogen, so the hydrogen in the dilute acid cannot be replaced. However, when air is present, copper can be oxidized to copper oxide, which then reacts with acids and slowly dissolves in these dilute acids.

Copper has good thermal conductivity.

Introduction: 1. Copper is a chemical element, and the chemical symbol is Cu (Latin: cuprum; English:

copper), the atomic number is 29, and it is a transition metal. Copper is the earliest metal used by humans. As early as prehistoric times, people began to mine open-pit copper mines, and used the obtained copper to make **, utensils and other utensils, and the use of copper had a profound impact on the progress of early human civilization.

Copper is a metal found in the earth's crust and oceans. The amount of copper in the earth's crust is about, and in individual copper deposits, the copper content can reach 3% to 5%. Most of the copper in nature is a compound that is a copper mineral.

Copper minerals are polymerized with other minerals to form copper ore, and the mined copper ore is beneficiated to become a copper concentrate with higher copper grades. It is the only metal that can be produced naturally in large quantities and is also found in various ores (e.g. chalcopyrite, chalcopyrite, bornite, chalcopyrite and malachite) and can be used in industry, engineering and processes in the form of elemental metals and brass, bronze and other alloys.

2. Silvery-white light metal. Malleable. Commodities are often made into rods, flakes, foils, powders, ribbons, and filaments.

In humid air, an oxide film can be formed to prevent metal corrosion. When heated in the air, the aluminium powder burns violently and emits a dazzling white flame. Soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, hydrophonotic sodium oxide and potassium hydroxide solutions, insoluble in water.

Relative density. Melting point 660 . Boiling point 2327.

The content of aluminum in the earth's crust is the third most abundant metal element in the earth's crust after oxygen and silicon. The development of the three important industries of aviation, construction and automobile requires the unique properties of aluminum and its alloys, which greatly facilitates the production and application of this new metal aluminum. It is extremely versatile.

Copper is a heavy metal element that is not very reactive. It does not react with oxygen in dry air at room temperature. But when heated, it can be oxidized to synthesize black copper oxide cuo:

Continued combustion at very high temperatures will produce red cuprous oxide Cu2O, which is toxic and is widely used in ship bottom paints to prevent parasitic plants and animals from growing on the bottom of ships.

In moist air, a layer of green patina slowly forms on the surface of copper, the composition of which is mainly basic copper carbonate

In the potential sequence, copper comes after hydrogen, so copper cannot react with dilute hydrochloric acid or dilute sulfuric acid to release hydrogen. But in air, copper can be slowly dissolved in dilute acids to form copper salts

Copper is easily dissolved by oxidation of oxidizing acids such as nitric acid or hot concentrated sulfuric acid.

At room temperature, copper can be directly combined with halogens, and copper can be directly combined with sulfur to form Cus. when heated

In addition, copper can also interact with ferric chloride. In the radio industry, FeCl3 solution is often used to etch copper to make printed lines.
