1.	What do you think? Should hydrogen be placed in the group 17 of halogens or group 1 of alkali metals in the Modern Periodic table?
Answer» Solution :(i)Hydrogen fits in its current position in theperiodic table (group 1) much better than ingroup 17 (THOUGH is not a perfect position). FOREXAMPLE Hydrogen forms oxide (`H_2O`) just likeoxides of alkali METALS `(Na_2O,K_2O)`. It has the same common charge ( + 1) as all alkali metals. (ii) It resembles halogens in forming diatomicmolecules `H_2,Cl_2,F_2,Br_2`. (iii) It does not behave like halogens, being mainly in the + 1 oxidation state. It does not happen to be like halogens, the most STABLE compounds of halogens have either -1 or a very high oxidation state like -7 or +5.) (iv) Hydrogen has one electron in the outermost shell and it is placed in top of group/based on atomic number.
