What are ion compounds?

ion compounds are chemical compounds that are connected by electrical charges of individually charged atoms of ions. Usually, the ion compound is composed of positively charged metals and negatively charged non -winter and form crystalline structures. Ordinary salt-nacl-is one of the most common ion compounds found in nature, consisting in a basic form of bond between a positive sodium atom and a negatively charged chlorine atom. Their fragility also gives them a tendency to break into the same smaller crystals if they are hit by sufficient force. Crystalline ion salts are also soluble in water and once they are dissolved in water or in a clean liquid, molten state, they are good electrical wires.

The naming of ionic compounds has always followed the tradition of using the first cation or a positively charged ion and attached the name of the negatively charged anion. Therefore, the salt is fromSodium chloride, with other examples being potassium iodide, silver nitrate and mercury chloride. The total number of atoms of a positive cation and atoms of negative anions is not included in the name structure, because any ion compounds balance these charges. The compound, such as silver nitrate with the chemical pattern Agno 3, does not require a plural for a group of nitrates. However, ion elements such as iron, which may have a positive charge of two or three, are commonly referred to as this charge, such as Fe +2 called iron (II).

In their natural form, ion compounds are never strictly ion or neutral and often have a certain degree of coval - sharing electrons between different atomic energy shells. Electnegativity is influenced by How's strong negative charge is in ion compounds, while the pauling scale considers fluorine as the most electronegative element at an evaluation of 4.0. Other elements such as cesium are the smallest electronOnegative at 0.7. This different levels of electronegativity is used to define covalent vs. ionic bindings. No difference in electronegativity between bound atoms is a pure, non -polar covalent bond, while a large difference in electronegativity represents an ion bond.

metals in nature are found in the form of ion compounds. This is because the metals are largely reactive with carbon and oxygen in the presence of water, as well as elements such as sulfur, phosphorus and silicon. Therefore, metal cleaning begins generally by mining of ionic compounds, such as sulphides, phosphates, carbonates and most often oxides to form pure elementary metals that can be used in industry.
