factors affecting the formation of metallic chemical bonding

Factors Favouring the Formation of a Covalent Bond - The following factors favour the formation of covalent bonds..

Low ionisation energy Ionisation energy is the amount of energy, which is required to remove the most loosely bound electron(s) from an isolated gaseous atom to form a positive ion. In forming an ionic bond, one atom must form a cation by losing one or more electrons. In gene..

Covalent or metallic bonds, ionic bonds Chemical bonds between atoms in molecules such as H2, CH4, NH3, H2CCH2, N2, Cl2 Electrostatic attraction in salt crystals such as NaCl Inter-molecular forces in a solid and liquid Lewis dot structure..

1) Charge on the central metal ion: Greater the charge, more the stability. 2) Basic nature of ligand: More the basic nature, more is the stability. 3) Presence of chelate rings: Formation of chelate rings increases the stability. Exampl..

Covalent Bonding - 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 a..

The electronic configuration of magnesium is 2,8,2 and that of nitrogen is 2,5. A magnesium atom needs to lose two electrons, whereas the nitrogen atom needs to gain three electrons to attain the octet. The chemical formula for magnesium nitride is Mg 3 N 2 . Ion formation..

Hydrides - The formation of binary compounds by hydrogen with other elements, are called hydrides. Hydrogen combines with most of the metals and non-metals (except noble gases). Hydrides are classified into three main types, depending upon their physical and chemi..

Born Haber Cycle - Based on Hess's law Born and Haber in 1919 developed a simplified and cyclic method to correlate lattice energies of ionic crystals to other thermodynamic data. For example, the net energy changes during the formation of sodium chloride from metallic sodium an..

Corrosion :- Many metals are chemically active elements and get easily affected by substances like moisture, air, acids, etc. One must have observed iron articles that are shiny when new, but get coated with a reddish brown powder when left for some time. This p..
