formation of more than one covalent bond

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..

. 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 ..

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 el..

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 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..

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 to as covalency and the b..

Covalent Bond - A covalent bond is defined 'as the force of attraction arising due to mutual sharing of electrons between the two atoms'. The combining atoms may share one, two or three pairs of electrons. The covalent bond is fo..

A covalent bond is defined 'as the force of attraction arising due to mutual sharing of electrons between the two atoms'. The combining atoms may share one, two or three pairs of electrons. The covalent bond is formed between two similar or dissimil..

Coordinate Covalent Bond or Dative Bond - When the shared electron pair is provided by one of the combining atoms, a coordinate bond is formed. The atom, which provides the electron pair is termed as the donor atom, while the other atom, which accep..
