directional bond

Since the covalent bond is localised in between nuclei of atoms, it is directional in natur..

The orbital overlap - 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 ..

Covalent bonds form due to mutual sharing of one or more pairs of electrons between two atoms. In a covalent bond, the shared pair of electrons remains localised in a definite space between the nuclei of the two atoms. This gives a directional character to the covalen..

The bond order conveys the following important information: (i) If the value of bond order is positive, it indicates a stable molecule and if the value of bond order is negative or zero, it means that the molecule is unstable. (ii) The stability of a molecule is mea..

Bonding in Covalent Solids - In covalent solids, the constituent particles are atoms of same or different kinds. Covalent bonds network, forming a continuous giant interlocking structure of atoms throughout the crystal that hold them together. They are also referred to as covale..

Orbital Representation of Covalent Bonds - 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: ..

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 made by the..

An ionic or electrovalent bond has the following characteristics: An ionic bond is formed due to the coulombic attraction between the positively and negatively charged ions. An ionic bond is non-directional i.e., the strength of interaction between two ..

The first theory was called the Werner's theory of co-ordination compounds. 1) Metals possess two types of valencies: a) Primary valency or ionizable valency. It is also referred to oxidation state. b) Secondary valency which a metal atom or cation exercises towards neutral molecules or negative gr..
