H(-) (He gas configuration), Cl + e -----> Cl(-) (Ar gas configuration). Hence, it can also be placed above the halogen group. ... Give the general group characteristic applied to hydrogen with respect to similarity in properties of hydrogen with halogens of group 17 [VIIA]. elements in group I-A. Copyright Notice © 2020 Greycells18 Media Limited and its licensors. resempblence with halogens(Group -17 or Group VII)--- (1)electronic configuration:-all halogens have 7 electrons in their repective outermost shell and thus have one less electron than the stable configuration of nearest noble gas ..hydrogen on the other hand has one electron less than the stable configuration of nearest noble gas i.e. The properties of hydrogen are different from the other members of its group i.e. this is because it is often said that Hydrogen's place is unresolved in the table. Middle School. Water is made up of hydrogen … Hydrogen can be in both group 1 and group 7 due to it's valence shell. Hydrogen 1s 1. Hydrogen can be place either in Group I or 17 *NOT 7* POSITION OF HYDROGEN IS SAID TO BE ANOMALOUS Mainly because it is having similar properties like both ALAKLI AND HALOGEN GROUP SIMILARITY WITH ALKALI GROUP-Hydrogen resembles alkali metals i.e. but it is a special case so we shall place hydrogen at top of pereiodic table. 1) Electronic configuration : Like alkali metals, hydrogen also contains 1 electron in its outermost shell. IT IS JUST PLACED ABOVE group 1 of th table as it has valency one and cannot be placed with halogens as it has just one valence electron. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Hydrogen's Placement in the Periodic Table.
