four properties of ionic compounds

General Properties of Ionic Compounds - The general properties of ionic compounds a..

Physical state Ionic compounds do not exist in the form of independent molecules but exist in the form of ions in crystalline solids, according to X-ray studies. These ions are arranged to form the crystal lattice in definite geometric pattern. For example, in NaCl ..

Formation of ionic compounds..

Ionic Radii - These are radii of ions in ionic crystals. Ionic radius may be defined as the effective distance from the center of nucleus of an ion up to which it has an influence on its electron cloud. In ionic compounds the inter nuclear distance ..

Compounds - A compound is a pure substance that is formed by the combination of atoms of two or more elements. The atom in a compound is chemically combined in a fixed and constant proportion. When compounds are formed, atoms of two or more elements combine c..

Comparison of Properties of Electrovalent and Covalent Compounds Property Electrocalent or ionic compounds Covalent or molecular compounds Structure of charged ions They consist of oppositely charged molecules They ..

Factoids - A chemical compound is always electrically neutral. The positive and negative valencies of the ions/radicals in a compound are equal and balance..
