Why Hydrogen is placed at the top of the periodic table and is not included in any particular group?
Asked by | 28 Nov, 2012, 06:26: PM
answered-by-expert Expert Answer
Hydrogen resembles the elements of group I-A, IV-A and VII-A in some respects. Properties of hydrogen do not completely match any one of the above-mentioned groups. That is why position of hydrogen is still undecided.
