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

Sodium nitrate belongs to the family of compounds called salts, which are formed by uniting an acid (nitric in this instance) with a base (in this case sodium hydroxide). When sodium nitrate is combined with hydrochloric acid, an exchange reaction occurs, producing sodium chloride and nitric acid. The salt and nitric acid can be separated from each other and the two substances can be put to practical used. The Reaction: In the symbols of chemical terminology, the reaction may be written as, NaNO3 + HCl ---> NaCl + HNO3 This says that one molecule of sodium nitrate reacts with one molecule of hydrochloric acid to produce one molecule of sodium chloride and one molecule of nitric acid. Sodium Chloride: one of the reaction products, sodium chloride, is readily available in nature, so this reaction is not a particularly useful source for that substance. Purified sodium chloride is ordinary table salt and in its impure state( halite) is used for a variety of purposes, including( among ma
