Chemical Properties Of Copper screw
| Property | Description |
|---|---|
| Chemical Symbol | Cu |
| Atomic Number | 29 |
| Density | 8.96 g/cm³ |
| Melting Point | 1,984°F (1,085°C) |
| Boiling Point | 4,643°F (2,562°C) |
| Oxidation | Copper reacts with oxygen to form copper oxide (CuO), which is a black or dark brown compound. Over time, this forms a greenish patina (copper carbonate, Cu₂(OH)₂CO₃). |
| Reactivity with Air | Copper is relatively stable in air but will gradually form an oxide layer (patina), which protects it from further corrosion. |
| Reactivity with Water | Copper is resistant to water corrosion but may tarnish over time when exposed to moisture. In chloride-rich environments, it is susceptible to stress corrosion cracking. |
| Reactivity with Acids | Copper dissolves in nitric acid (HNO₃), forming copper nitrate (Cu(NO₃)₂). It is largely resistant to sulfuric acid (H₂SO₄), hydrochloric acid (HCl), and other non-oxidizing acids. |
| Reactivity with Alkalis | Copper is generally resistant to most alkalis (bases), but may react with ammonia to form complex copper-ammonia compounds. |
| Reactivity with Chlorine | Copper reacts with chlorine gas (Cl₂) to form copper(I) chloride (CuCl) or copper(II) chloride (CuCl₂) depending on the conditions. |
| Electrical Conductivity | High electrical conductivity (approximately 97% IACS for pure copper), which is why copper screws are used in electrical applications. |
| Thermal Conductivity | High thermal conductivity, making copper screws ideal for heat dissipation in various systems. |
| Corrosion Resistance | Excellent resistance to atmospheric and water corrosion, particularly in non-acidic environments. However, copper may corrode in the presence of sulfur or ammonia. |
| Reactivity with Hydrogen | Copper is generally resistant to hydrogen attack under normal conditions. However, in very high-temperature environments, copper may form copper hydrides. |
| Passivation | Copper screws naturally passivate over time, forming a protective oxide or carbonate layer that prevents further corrosion. |
