Why do atoms react, and how? Atoms having eight electrons in their last orbit are stable and have no tendency to react. Atoms having less than eight electrons then react with other atoms to get eight electrons in their outermost orbit and become stable. Atoms having slightly excess than eight electrons may lose them to…

Bond Length During chemical bonding, when the atoms come closer to each other, the attraction takes place between them, and the potential energy of the system keeps on decreasing till a particular distance at which the potential energy is minimum. If the atoms come closer, repulsion starts, and again, the potential energy of the system…

The following steps are adopted for writing the Lewis dot structures or Lewis structures: Step 1: Calculate the number of electrons required for drawing the structure by adding the valence electrons of the combining atoms. For example, in methane, a CH4 molecule, there are 8 valence electrons (of which 4 belong to carbon while the other 4 to H…

In 1916, Kossel and Lewis succeeded in giving a successful explanation based upon the concept of an electronic configuration of noble gases about why atoms combine to form molecules. Atoms of noble gases have little or no tendency to combine with each other or with atoms of other elements. This means that these atoms must have stable…

Albrecht Kössel and Gilbert Lewis were the first to explain the formation of chemical bonds successfully in the year 1916. They explained chemical bonding on the basis of the inertness of noble gases. Lewis Theory of Chemical Bonding Lewis symbols for lithium (1 electron), oxygen (6 electrons) and neon (8 electrons) are given below. Here, the…

Chemical bonding refers to the formation of a chemical bond between two or more atoms, molecules or ions to give rise to a chemical compound. These chemical bonds are what keep the atoms together in the resulting compound. Table of Contents The attractive force which holds various constituents (atoms, ions, etc.) together and stabilises them by…

Q1 What is salt in acids, bases and, salts? In chemistry, a salt is a substance obtained by the reaction of an acid and a base. Salts are composed of positive ions (cations) of bases and negative ions (anions) of acids. The reaction of acid and base is called the neutralization reaction. Q2 Is NH4Cl…
