Why the position of hydrogen is misfit in Group 1A of Periodic Table?
If you consider that hydrogen is a misfit in Group 1A of the periodic table, then can I ask – Where would you place it so that it is not a misfit? There is no place on the periodic table where it can be placed perfectly. The easiest reason to understand why it is placed at the top of Group 1 is because it has 1 single electron in its outer shell – like all Group 1 elements. However, I do not see on most periodic tables that hydrogen is actually part of Group 1. On my periodic table hydrogen is placed at the top left hand corner of the table, but it is given a different colour to the elements in Group 1 – which indicates that it is not really part of that Group. Hydrogen must be considered as a special case. With atomic number 1, it should be placed at the beginning of the table, which is the top left hand corner. You could very well ask: Why is helium, atomic number 2, with 2 electrons in its outer shell, not in Group 2, but is in Group 8?
