Carbon Family: Introduction,Atomic properties, Physical properties, Chemical properties,Anomalous Behaviour of carbon, Allotropes of carbon, Compounds of carbon and Compounds of silicon. INTRODUCTION: Group 14 elements are Carbon C, silicon Si, germanium Ge, tin Sn, and lead Pb.Carbon is the seventeenth most abundant element by mass in the earth's crust. It is.widely distributed in nature in free as well as in the combined state. In elemental state it is available as coal, graphite and diamond; however, in combined state it is present as. metal carbonates, hydrocarbons and carbon dioxide gas (0.03%) in air. One can emphatically say that carbon is the mostversatile element in the world. Its combination. with other elements such as dihydrogen, dioxygen, chlorine and sulphur provides an. astonishing array of materials ranging from living tissues to drugs and plastics. Organic. chemistryis devoted to carbon containing compounds. Element: Carbon CAtomic number: 6Atomic weight: 12.011 Element: Silicon Si Atomic number: 14 Atomic weight: 28.09 Element: Germanium Ge Atomic number: 32 Atomic weight: 72.59 Element: Tin Sn Atomic number: 50 Atomic weight: 118.7 Element: lead Pb Atomic number: 82 Atomic weight: 207.2 Element: Uuq Atomic number: 114 Atomic weight: 289 Carbon:Carbon is the 17th most abundant element in the earth's crust by mass.In elemental state, carbon is available as coal, graphite and diamond.The common carbon compounds in the earth environment include the gases Carbon dioxide and methane. Silicon:The name for silicon is taken from the Latin silex which means "flint".Silicon is the second most abundant element in the earth's crust 27% by mass.Silicon is the important component of ceramics, glass and cement.The most common compound of silica is Silicon dioxide.
