Metallic Bond
The attractive force, which binds various metal atoms, is called metallic bond. The metallic bond is neither a covalent nor an ionic bond..
Bonding in Metallic Solids
Bonding in Metallic Solids - More than 80 elements in the periodic table are metals. Metals are solids at ordinary temperature and pressure, with the exception (of mercury and gallium). Metals have characteristic properties such as: High thermal and..
Metallic Bond (Band Theory)
Metals constitute about three fourths of all the known elements. They have characteristic properties such as bright luster, high electrical and thermal conductivity, malleability, ductility and high tensile strength. The attractive force, which binds various metal atoms, i..

Electron sea model for metallic bonding
To account for the bonding in metals, Lorentz proposed a model known as electron gas model or electron sea model. This model is based on the following characteristic properties of metals..
Bond Energy or Bond Enthalpy
In chemical reactions the formation of a chemical bond is accompanied by the release of energy. Conversely energy has to be supplied for the breaking of a bond. Bond strengths are commonly described by their bond dissociation energy which is the energy requir..
Metals and Non-metals
Earth is an abundant source of material. Man has intensively studied the properties of these materials extensively and found new methods of using them. The air we breathe, the water we drink, stones and rocks, almost everything that is around us, are all useful to man for ..
Metals and Non-metals
The progress of the civilization was first benchmarked by man's increasing knowledge and usage of metallic deposits in the earth's crust. Early man used stones, bones and wood to fulfill their requirements of hunting, cooking and buildin..
