Metallic Bond (Band Theory)
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, ..
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..

Combination with non-metals
Hydrogen, like the alkali metals, combines readily with non-metals like halogens, oxygen, sulphur, et..
Combination with non-metals
Hydrogen combines with non-metals, to give the respective hydrides. With oxygen Hydrogen burns in oxygen to form water. Instead of igniting the mixture, if a small quantity of well divided platinum is added to the mixture of the two gases, they instantly combine t..

Instead of igniting the mixture, if a small quantity of well divided platinum is added to the mixture of the two gases, they instantly combine t..Electronic Nature of Metals and Non-metals
We are familiar with the fact that the atoms of all elements, except noble gases, have an incomplete outermost shell. Consequently, most elements are reactive and they try to achieve the stability of the noble or inert gases by electron transfer or by electron sharing. After this combinationh..
Covalent Bonding
Covalent Bonding - When the combining atoms have 4, 5, 6, or 7 electrons in the outermost or valence shell, they cannot donate electrons. Instead, they mutually share electrons in order to complete their octet in the outermost orbit or shell. Such a type of valency is referred t..
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..
