Group 14 elements notes. . 1 G r o u p 14. The atomic radii increase down the group, and ionization energies decrease. Carbon is an essential constituent of all living matter. Group 14 elements The elements in this group range from a non-metal, carbon to the metals tin and lead, with the intervening element – germanium showing semi metallic (metalloid) behaviour. Group 14 elements, comprising carbon, silicon, germanium, tin, and lead, demonstrate varied properties from nonmetal to metallic behaviors. All these are cage-like spheroidal molecules having polyhedral geometry containing pentagonal and hexagonal planes. Down the group, the metallic character increases. Structure Of Fullerenes C60: Fullerenes are expressed by the general formula Cn, where n is an even number between 30-600, for example, C 60, C 70, C 84 …. These elements display unique properties and trends as you move down the group, such as changes in electronegativity, atomic size, and oxidation states, which are crucial for understanding their chemical behavior and applications in various fields.

The Group 14 elements tend to adopt oxidation states of +4 and, for the heavier elements, +2 due to the inert pair effect. Occurrence Carbon has been known as the charcoal resulting from partial combustion of organic matter. Group 14 elements are less electropositive than group 13 owing to their small size and high ionization enthalpy. etc. Group 14 elements, also known as the carbon group, consist of carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl). 1: Group 14 in the Periodic Table Members of this group conform well to general periodic trends.
