Question

Why hydrogen can be placed in either group 1 or group17 of the periodic table?

Answer 1

Answer:

Hydrogen has single electron and its atomic number is one so its placed first. moreover some of its properties match with alkali metals and so its placed in group 1. although it has properties similar to those of halogens too and can be placed in group 17 too. Its position is anomalous.

ANSWER :

Hydrogen can be placed in both group 1 and group 17 because its electronic configuration is similar to both the groups.

Like group I elements, hydrogen has only one electron in its valence shell. Thus it can lose an electron to achieve a stable configuration like alkali metals and hence can be placed in group 1 (alkali metals).

However, like group 17 elements, it requires only electron to complete its valence shell, thus it can also gain an electron to achieve a noble gas configuration.
