%�쏢 Octet Rule. This phenomenon of deformation of anion by a cation is known as polarisation and the ability of cation to polarize a nearby anion is called as polarizing power of cation.Fajan’s pointed out that greater is the polarization of anion in a molecule, more is a covalent character in it.Fajan’s gives some rules which govern the covalent character in the ionic compounds, which are as follows :It forms by sharing of valence electrons between atoms to form molecules e.g., formation of ClThe Lewis dot structures can be written for other molecules also, in which the combining atoms may be identical or different.

There are three types of exceptions to the octet rule.In some compounds, the number of electrons surrounding the central atom is less than eight. The conversion factors areFurther dipole moment is a vector quantity and is depicted by a small arrow with tail on the positive centre and head pointing towards the negative centre.
Revising notes in exam days is on of the best tips recommended by teachers during exam days.

The solid crystal being three dimensional; it is not possible to calculate lattice enthalpy directly from the interaction of forces of attraction and repulsion only. Mulliken in 1932. Hybridization: The structures of different molecules can be explained on the basis of hybridization. These are the Chemical Bonding and Molecular Structure class 11 Notes Chemistry prepared by team of expert teachers. It is expressed as :The atoms have been numbered as 1.2 and 3. Therefore, the type of hybridisation indicates the geometry of the molecules. (iii) An electron in an atomic orbital is influenced by one nucleus, while in a molecular orbital it is influenced by two or more nuclei depending upon the number of the atoms in the molecule. To explain the tetravalency of carbon, it was proposed that one of the electrons from 2s filled orbital is promoted to the 2p empty orbital (2p z), which is in a higher energy state.
For e.g., in case of carbon, the ground state electronic configuration is 1s 2 2s 2 2p 1 x 1 y. (a) By Coordinate bond formation: Generally in halides of atoms having vacant d-orbitals.
The attractive force which holds various constituents such as atoms, ions etc., together in different chemical species is called a chemical bond. The increasing order of energies of various molecular orbitals for OThe increasing order of energies of various molecular orbitals for BeThe important characteristic feature of this order is that the energy of Bond order (b.o.)

Membership feels like a huge effort towards a strong, diverse community of people who care about their Education. (vii) The molecular orbitals like the atomic orbitals are filled in accordance with the Aufbau principle obeying the Pauli Exclusion principle and the Hund’s Rule of Maximum Multiplicity. Students can download the FREE PDF of ICSE Class 10 Chemistry Chapter 2 Chemical Bonding Revision Notes and use it to clear all their doubts and queries and hence, excel in their examination. The ability of metals to conduct electricity and heat must result from strong electrons interactions among 8 to 12 nearest neighbours (which is also called coordination number).
These hybrid orbitals are directed in space in some preferred direction to have minimum repulsion between electron pairs and thus a stable arrangement is obtained.
