what is valence bond theory on metallic bonding

The metal ligand bond arises by donation of pair of electrons by ligands to the central metal ato..

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 attracti..

Drawbacks of Valence Bond Theory - 1) It is a qualitative approach describing bonding in coordination compounds. 2) The theory fails to explain the optical absorption spectra and magnetic properties of coordination compounds. 3) The theory..

Although the Lewis structures give an idea of the valence electrons around the atom, in reality it does not precisely locate the position of the electrons in the chemical bond. The behaviour of electrons in molecules and compounds is made by the valence bond..

. The atom of metallic elements contain only 1 to 3 valence electrons, therefore these atoms cannot form covalent bonds, with noble gas configurations as they will remain incomplete. Covalent compounds are bad conductors of electricity and are generally liquids; proper..

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 ..

Can we imagine a world without oxygen, nitrogen, water or carbon dioxide? Without any of these there would be no life at all. All the above mentioned compounds are covalent compounds formed by sharing of electrons. Non-metal atoms share the valence electrons and form molec..
