1.	Why Hydrogen is listed in periodic table although it is Nonmetal?
Answer» Hydrogen is a nonmetal and is placed above group in the periodic table because it has ns1 electron configuration like the alkali metals. However, it varies greatly from the alkali metals as it forms cations (H+) more reluctantly than the other alkali metals It is used as a reference element to compare reactivities of metals Hydrogen\xa0is a nonmetal and is placed above group in the\xa0periodic table\xa0because it has ns1\xa0electron configuration like the alkali\xa0metals.\xa0However, it varies greatly from the alkali\xa0metals\xa0as it forms cations (H+) more reluctantly than the other alkali\xa0metals.
