  2. General Physical Properties of Group 14 Elements (i) Electronic configuration Their valence shell electronic configuration is ns np Atomic Number Period NumberNumber Group Carbon Silicon Germanium Tin Lead Electronic Configuration [He] 2s2 2p2 [Ne] 3s 3p Arl 3d10 4s2 4p [Kr] 4d10 5s2 5p* [Xe] 4f4 5d10 6s2 6p2 14 14 14 14 14 2 14 32 50 82


  3. (ii) Metallic character C and Si are non-metals, Ge is a metalloid and Sn and Pb are metals. (iii) Appearance C is black. Si is light-brown, Ge is greyish, Sn and Pb are silvery white. (iv) Density Density increases with increase m atomic number due to increase in mass per unit volume down the group. (v) Melting points and boiling points The melting points and boiling points decrease from carbon to lead but carbon and silicon have very high melting and boiling points due to their giant structure. (vi Oxidation state They exhibit +2 and +4 oxidation state. The compounds of Pb in +4 oxidation state are powerful oxidising agents since, +2 oxidation state of Pb is more stable due to inert pair effect
