describe chemical bonding

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 and form mo..

. Greater the difference in the electronegativities of the atoms forming the bond, greater will be the charge separation and hence greater will be the polarity of the molecule Distorted electron cloud Similarly, molecules such as BrCl, H 2 O, HF, etc. are also polar molecul..

. This may be represented as: The hydrogen atom acts as a bridge between two atoms, holding one atom by a covalent bond and the other atom by a hydrogen bond. The hydrogen bond is represented by dotted line (....) while the covalent bond is represented by sol..

Elemental state and chemical reactivity - Nitrogen is a colorless gas and exists as diatomic. The two nitrogen atoms are held together by triple bond and have very high bond dissociation energy (945 kJ mol - 1 ..

Chemical Combination - The force which holds together the ions, atoms and molecules in a chemical substance is called as chemical bond. It is the same force which makes substances combine with each other in many different ways to give newer products. The comb..

Trends in Chemical Reactivity - As in the case of S, the important oxidation states observed for Se and Te are also 2, +2, +4 and +6. The chalcogenide dianions (E 2 - ) exist only in their compounds with the most electropositive elements. By and large, chalcogens with the exception of pol..

Covalent bonds are formed by the overlap of atomic orbitals. As orbitals have different shapes, it is difficult to represent the actual shape of the orbitals on the paper. Hence a pictorial notation is adopted with the following rules: An orbital is represented by a square box ( ) or a..

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 theo..

Bonding in Solid State (Additional) - Solids are closely packed condensed states, with their constituent particles (atoms, ions or molecules) held together by strong physical or chemical bonds. These particles show a definite regular arrangement in a long range order. ..
