covalent bond formation

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

High ionisation energy Elements that have higher ionisation energies cannot form ionic bonds, as they cannot lose electrons easily. Instead, they acquire stability by mutual sharing of electrons, and therefore form covalent bonds..

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 e..

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..

. In the previous chapter one has observed the formation of a chemical bond by the transfer of electrons called the ionic bond. Atoms also acquire the stable noble gas configuration of having eight electrons in the outermost shell (called the octect rule) by mutual sha..

The number of electrons, which an atom contributes towards mutual sharing during the formation of a chemical bond is called its covalency in that compound. Thus, the covalency of hydrogen in H 2 (H - H, H : H) Sometimes one or more pairs of electrons in..

The bond between two unlike atoms, which differ in their affinities for electrons is said to be a polar covalent bond. When a covalent bond is formed between two atoms of different elements, the bonding pair of electrons will lie more tow..

Quantum Theory of Covalent Bond - 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 m..

The sharing of orbitals between two atoms is possible only when the atoms are close enough to overlap their orbitals. Thus, orbital overlap is necessary for the sharing of electrons and bond formation. With the orbitals coming close together, there is an increase in the el..

Triple Covalent Bond - A triple covalent bonds consists of three pairs of shared electrons. It is formed by the sharing of three pairs of electrons between two atoms. In all there are six electrons shared between two atoms. It is a combination of three single..
