family group dynamics

Carbon (C), silicon (Si), germanium (Ge), tin (Sn) and lead (Pb) constitute the group 14 of the periodic table. This group is known as carbon family..

Group 15 of the Periodic table includes five elements namely nitrogen (N), phosphorus (P), arsenic (As) antimony (Sb) and bismuth (Bi). This group is regarded as nitrogen family. There is a transition from non-metallic to metallic character as we go down the ..

Group 13 of the periodic table consists of the elements boron (B), aluminium (Al), gallium (Ga), indium (In) and thallium (Tl). Except boron, which is classified as a non-metal, all other elements of this group are metal..

Group 17 of the periodic table contains the elements fluorine, chlorine, bromine, iodine and astatine. These elements are collectively known as the HALOGENS. This name is derived from two Greek words Halo and Gens meaning 'salt producing'. Halogens are among the most reactive non-me..
