The Chemistry of Carbon Compounds

Structure and bonding in metals: Metals consist of giant structures of atoms arranged in a regular pattern. The electrons from the outer shell of the metal atoms are delocalised and are free to move through the whole structure. This sharing of Delocalised electrons results in a strong metallic bond. Metallic bond:  Metallic bonds formed when the charge is spread over a large distance as compared to the size of a single item in a solids. Mostly in the periodic table, left elements form metallic bonds, for example zinc and copper. Because metals are solid, their atoms are tightly packed in a regular arrangement. They are so close to each other so valence electrons can be moved away from their atoms. A sea of free, Delocalised electron is formed surrounding a lattice of positively charged metal ions.These ions are held by strong attractive forces to mobile electrons,in this way, metallic bonds are formed. Structure of metals: The three most common crystalline structures in metals are face

What is metal plating? The plating process is a manufacturing process in which a thin layer of metal coats a substrate. Metal plating provides many benefits to products made from metal and other materials. This mostly achieved through electroplating, which requires an electric current, or through electroless plating, which is in the autocatalytic chemical process.  Benefits of plating: Improved corrosion resistance Decorative appeal Increased solderability Enhanced hardness  Reduced friction Enhanced paint adhesion Altered conductivity Increased magnetism material deposition Types of metal plating: Copper plating Copper is a popular plating metal for applications that require high conductivity and cost-efficiency. Copper plating often serves as a strike coating pretreatment for subsequent metal platings. It is a popular plating metal for electronics components such as printed circuit boards. High plating efficiency and low material cost make copper one of the less expensive metals to p
