Copper coil is a chemical element, its chemical symbol is Cu (Latin: Cuprum), its atomic number is 29, and it is a transition metal. Copper is a purple-red lustrous metal with a density of 8.92 g/cm3. Melting point 1083.4±0.2℃, boiling point 2567℃. Common valences +1 and +2.

The ionization energy is 7.726 electron volts. Copper is one of the earliest metals discovered by human beings, and it is also one of the good pure metals. It is slightly hard, extremely tough and wear-resistant. There is also good ductility.

Good thermal and electrical conductivity.

Copper and some of its alloys have good corrosion resistance and are stable in dry air. But in humid air, a layer of green basic copper carbonate Cu2(OH)2CO3 can be formed on its surface, which is called patina. Soluble in nitric acid and hot concentrated sulfuric acid, slightly soluble in hydrochloric acid. Easily attacked by alkali.
