Group 14 of the Periodic Table – Chemistry’s Versatile Elements

The Group 14 of the Periodic Table consists of six elements; carbon (कार्बन), silicon (सिलिकॉन), germanium (जर्मनियम), tin (टिन), lead (लेड) and flerovium (फ्लेरोवियम). Popularly known as the carbon family, these elements are known for their tremendous versatility and countless applications. Though their individual properties vary greatly, all of them have four valence electrons in their outermost shell and are highly electronegative. They are non-metals, with the exception of tin.

Properties of Group 14 Elements

The physical and chemical properties of the group 14 elements vary greatly with their atomic size and structure. Carbon and silicon are two of the most abundant elements on earth, accounting for more than three-quarters of the Earth’s crust. Both have low melting points and densities, and exist in a variety of solid, liquid and gaseous forms. Carbon is an excellent conductor of electricity and forms strong covalent bonds with other atoms and molecules. Silicon is a semiconductor, capable of both aiding and inhibiting the flow of electricity. Germanium and Tin have moderate melting points, while lead has a high melting point and forms compounds with many other elements, including sulfur and oxygen. Flerovium is the densest and most radioactive member of the group, with a half-life of less than a second.

Uses of Group 14 Elements

The group 14 elements have a wide range of uses. Carbon is the basis of all life on earth, and is key for the formation of organic compounds, including proteins, fats and carbohydrates. It is also used to make industrial products, such as plastics, fuels and paints. Silicon is widely used in the computer industry, both as an insulating material and an electrical conductor. It is also used to make solar cells, which convert sunlight into electricity. Germanium forms alloys with other metals, used in the manufacture of transistors and integrated circuits. Tin is primarily used as a protective coating on steel and other metals, while lead is used to form lead-acid batteries, radiation shielding materials and ammunition. Flerovium is one of the most recently discovered elements, and is used in nuclear research.

Key Differences between Group 14 Elements

Given below is a comparison between the properties of the group 14 elements:

Conclusion

Group 14 elements of the periodic table, often referred to as the carbon family, comprise of six elements; Carbon, Silicon, Germanium, Tin, Lead and Flerovium. These elements are highly versatile, with a wide range of uses in the fields of science and technology. Though their individual properties vary greatly with the atomic number, all of them share a common property of having four valence electrons in their outermost shell. With more research into their properties, these elements could prove to have even greater applications in the future.
