chemical formulae of all compounds

A compound is a pure substance that is formed by the combination of atoms of two or more elements by either transfer or by sharing of electrons. The atoms of the different elements in a compound are chemically combined in a fixed and constant proportion. If this propor..

Most of the carbon-containing compounds associated with hydrogen i.e., hydrocarbons are fuels that produce heat on burning. Petroleum products like natural gas, petrol, diesel, kerosene, heavy oils etc., and in a larger sense, wood, biogas, charcoal and coke are all rich source of carbon..

Introduction - Sodium belongs to Group I in the periodic table. This group is otherwise known as the alkali metals group. Since the atomic number of sodium is 11, its electronic configuration is 2,8,1. Sodium easily loses the lone electron to attain the stable configuration of neon. Therefore alkal..

Ammonia and Ammonium Compounds - (i) By treating excess ammonia with chlorine, ammonium chloride and nitrogen are formed. The products obtained are bubbled through water. The vapours of ammonium chloride dissolve in the water while nitrogen is collected separately. (ii) By passing ammonia..

Chemical reactivity of halogens - The halogens are the most reactive elements as a family. Fluorine is the most reactive of all the halogens. The reactivity of the halogens decreases down the group. The high reactivity of halogens is due to the following reason..

The reactivity of metals decreases from left to right in a period while the reactivity increases down the group. The reactivity of non-metals increases from left to right in a period while the reactivity decreases down the gro..
