Justify the position of Hydrogen in the periodic table.

Text Solution

Verified by Experts

Hydrogen has been placed at the top of the alkali metals family.
Hydrogen and alkali metals resemble in the following aspects.
1. Electronic configuratin: Hydrogen has one electron in its valance shell like the alkali metals `H-1s^(1)`.
2. Electropositive character: As both hydrogen and alkali metals form monovalent cations by losing the electron in the valance shell. `HtoH^(+)+e^(-)`
