Physical and Chemical Properties of Group 14 Elements

 

Physical Properties of Group 14 Elements

This group consists of carbon, silicon, germanium, tin, and lead. The outer electronic configuration of the elements of this group is ns2 np2 whereas n is variable and it varies from 2 to 6. The elements of this group exhibit the covalent oxidation state of +4.

Carbon is the first element of this group and is different from the other members due to its high electronegativity, absence of d orbitals and small size. The group is starting from the element that is non-metal and the last elements are non-metals. The metallic character increases in descending the group.

The first element is non-metal, silicon is the metalloid and germanium is the non-metal but it possesses some of the metallic characteristics, whereas tin and lead are the metals.
