Question

Class 11 .justify the position of hydrogen in the periodic table on the basis of its electronic configuration

Answer 1

Hello dear
here is your answer
Hydroge is the first element of the periodic table.it's electronic configuration is (1s1).due to the presence of only one electron in its 1 s shell,hydrogen exhibits a dual behaviour.
hope it helps u

Answer 2

Answer :

Hydrogen has been placed at the top of the alkali metal in group, but it is not a member of the group.

Its position is not justified properly because of its electronic configuration as (1s1). It can be placed with alkali metals because it also has similar configuration (ns1) as alkali metals.

However, it can also be placed along with halogen in group 17 since just like halogen it can acquire inert gas configuration by accepting one electron.
