Why could no fixed position be given to hydrogen in Mendeleev's periodic table?

Text Solution

Verified by Experts

Hydrogen resembles alkali metals in its electronic configuration and halogens as it also exists as a diatomic molecule and combines with metals and non-metals to form covalent compounds hence it could not be assigned a fixed position in Mendeleev.s periodic table.
