Coordinate Bond

Certain atoms which have complete octets can donate their valence electrons which are not involved in bond formation ,to other atoms, which are short of electron. These donated electrons are, therefore, lone pair of electrons and are shared by both the atoms. When in the formation of a bond, the electron pair is donated by …

Fajan’s Rules

When a cation approaches an anion, the electron cloud of the anion is attracted towards a cation and hence gets distorted. The effect is called polarisation of the anion. The power of cation to polarise anion is called its polarising power and tendency of the anion to get polarised is called polarisability. The greater is the polarisation …

Dipole Moments

In a polar molecule, there are two poles present in the molecule.Hence, the molecule is said to possess an electric dipole.Since the molecule as a whole is electrically neutral ,the negative charges is always equal in magnitude to the positive charge. The product of magnitude of negative or positive charge(q) and the distance between the …

Bond Characteristics

Bond Length When atoms come closer to each other, attraction takes place between them and ,therefore, the potential energy of the system keeps on decreasing till at a particular distance, the potential energy is minimum. If the atoms are further brought closer ,the repulsion start and therefore, the potential energy of the system begins to …

Covalent Bond

The bond formed between the two atoms by mutual sharing of electrons between them so as to complete their octets or duplets in case of elements having only one shell is called covalent bond and the number of electrons contributed by each atom is known as covalency. Examples Two chlorine atoms combine to produce chlorine …

Ionic Bond

When a bond is formed by complete transference of electrons from one atom to another so as to complete their outermost orbit by acquiring 8 electrons or 2 electrons in case of hydrogen, lithium etc and hence acquire the stable nearest noble gas configuration, the bond form is called ionic bond or electrovalent bond. On …

Lewis Symbols

A group of atoms existing together as one species and having characteristic properties is called a molecule. This force which holds the atoms together within a molecule is called a covalent bond. Noble gases neither combine chemically with any other element nor among themselves i.e.they are chemically inert. Noble gases are inactive or stable because …
