element is used as a general block level element

Introduction - The p-block contains several elements of great social and economic importance as well as chemical interest. Examples include the use of aluminium as a structural material, the importance of silicon and germanium as semiconductors, and the use o..

's' block elements, (except helium) are those in which the valence-shell is the 'ns' orbital and where the last electron enters into the 's' orbital of the outer element. The general outer electronic configuration of such elements is either ns 1 or..

Introduction - The elements that lie in between S-block and P-block are the d-block elements. These elements are called transition elements as they show transitional properties between s and p-block elements. ..

Abundance and occurrence - Alkali and alkaline Earth metals are the most violently active of all the metals. These occur in the combined form with halide, sulphate, carbonate, silicate ions, etc. and are not found in the free state in nature, as these are readily oxidized. A number of alkali and al..

Most of the transition elements of the first row form metallic bonds due to the presence of incomplete outermost energy level. So, all the transition elements exhibit metallic characters. The strength of the metallic bond depends upon the number of unpaired d-ele..

'd' block elements are those in which the added electron goes into one of the 'd' orbitals. These elements have valence electrons in both their outermost and penultimate shells (second outermost) and have a general outer electronic configuration of (n - 1) d..

Summary - Carbon is the eleventh most abundant element in the earth's crust by mass. Carbon is the first member of group IVA and a typical non-metal. Carbon exhibits allotropy and shows maximum catenation. Carbon occurs both in free state as diamond, coal etc. and also in the combined for..

General Principles of Organic Nomenclature - Organic chemistry deals with about 5 million compounds containing carbon as an essential element. Remembering the name of each individual is not possible. Therefore, a system of nomenclature has been devised to name these compounds. T..
