H + + e-). have 1 valency. Thus it can lose an electron to achieve a stable configuration like alkali metals and hence can be placed in group 1 … Example. please remember ther is some space between the group 1A and Hydrogen. elements in group I-A. Hence, it can also be placed above the halogen group. Each water molecule (H 2 O) contains two hydrogen atoms. The valance electronic configuration of hydrogen is the same with the group 1A elements. Hydrogen can be placed in both group 1 and group 17 because its electronic configuration is similar to both the groups. The most common place to find hydrogen on earth is in water. Solution: Hydrogen element has been placed at the top of group 1, above the alkali metals because the electronic configuration of hydrogen is similar to those of alkali metals. Still, If I'd be Moseley I'd place it above the alkali metals. it has le, IP in nucleus. Like halogens, hydrogen is a gas, and exists as a diatomic molecule (H2). 2) In some other properties, hydrogen resembles halogens.As such, it can be placed in group 17 along with halogens. Hydrogen can be placed in group 1[1A] as it forms a positive ion as in HC1 like alkali metals H. Question 2. In the coming lines we will discuss why hydrogen can not be placed in a particular group in the periodic table. [11] The two hydrogens are the same, but some periodic tables show hydrogen in both places to emphasize that hydrogen isn't really a member of the first group or the seventh group.
