"Hydrogen can be placed either in group 1 or in group 17". Do you agree with this statement
or disagree? Give reasons.

Verified answer

Yes it can be placed in either of the groups.
-----------------------------------------------------------------------
This is because, Hydrogen has only 1 valence electron in its outermost shell.Like the Group I Alkali metals it has valency = 1 i.e it can lose electron.

Similarly, it can gain one electron to achieve stability.Like Group 17 elements,it can gain electron.

So its possible that hydrogen can be placed in both.

Hope This Helps You!

Hydrogen has 1 valence electron so it is placed in grp 1 . Moreover its properties match with those of halogens. So it can beplaced in grp 17 too
