The Carbon Family
Class 11 Chemistry Chapter 11 The p-Block Elements Carbon family include elements Carbon(C), Silicon (Si), Germanium (Ge), Tin (Sn), Lead(Pd). The general electronic configuration of this family is ns2 np2 that means these elements have valency 4. In nature Carbon is seventeenth most abundant element by mass in earth’s crust. However, carbon is found in […]
Chemistry of Alkaline Earth Metals
Class 11 Chemistry Chapter 10 s-block elements Alkaline earth metals are also known as Group II elements. These elements are Beryllium, Magnesium, Calcium, Strontium, Barium and Radium. The name alkaline earth suggest that these metals form alkalies with water and are found in earth’s crust. In this article let’s discuss in detail about alkaline earth […]
Alkanes – The Saturated Hydrocarbons
Class 11 Chemistry Chapter 13 Hydrocarbons Alkanes are the saturated hydrocarbon in which carbon and hydrogen also, carbon and carbon are linked with single bond. Among alkanes, methane is the first member of the family. Second member of family is obtained by replacing one hydrogen atom with carbon atom and by joining sufficient amount of […]
What is Air Pollution?
Class 11 Chemistry Chapter 14 Enviromental Chemistry Air pollution is the addition of unwanted component in air that causes harm to living organisms. Air pollution is nothing but atmospheric pollution. Atmospheric pollution is generally studied as tropospheric pollution and stratospheric pollution. Tropospheric pollution occurs due to undesirable solid or gaseous particle in the air. It […]
