common chemical compounds

Industrial and municipal waste waters and mine run offs cause various metals and metallic compounds to be released into water. These pollutants also enter the water bodies as acid rain and their sulphate and nitrate ions make water acidic. Most inorganic compounds are toxic, pa..

Lewis Structures of Some Covalent Compounds - The steps in writing Lewis structures of covalent compounds are as follows: of the molecule by placing the atoms of the combining elements properly. Usually an atom, which forms the largest number of bonds with other atoms is written..

Some common processes are precipitation, coagulation and disinfection..

A stable chemical compound has less energy than its separated parts, the difference being in the specific arrangement and motion of electrons and nuclei in the compound. This difference is called chemical energy or energy of chemical binding. In a ..

Every chemical substance is known by a specific name. But many a times these names are cumbersome, confusing, and do not provide information about its chemical composition. To overcome this, each chemical compound is represented by a chemical formul..

There are just 26 alphabets in English language, but the number of words are innumerable. You have studied about the 115 known elements and how they are classified for systematic and comprehensive study. Thousands of compounds are born by various chemical reactions involvi..

Combination of Elements - Atoms of elements combine to form molecules of compounds. This combination can occur in two ways: either by electrovalent bonding or covalent bonding. In all chemical reactions it is the electrons from the outermost shell of an atom that are involved in..

Ethers are relatively inert compounds inspite of the presence of oxygen atom carrying two lone pairs of electrons in their molecules. These are not easily attacked by alkalis, dilute mineral acids, metallic sodium, PCl 5 etc. under ordinary conditions. It is because of this reason that th..

The noble gases are generally inert and do not participate in the reactions easily. The inertness of noble gases is due to the following reasons. i) The atoms of noble gases have stable closed shell electronic configuration. ii) The noble gases have exceptionally high ionization energies. iii) ..
