Question

Compare hydrogen with the alkali metals on the basis of: ion formation. ​

Answer 1

Hydrogen shows electropositive nature like alkali metals due to similar electronic configuration.​

Alkali metals	Hydrogen
Alkali metals (Li, Na etc.) have one electron in the valence shell and they donate one electron to attain inert gas electron configuration.​	Similarly, hydrogen has one electron in the valence shell and hydrogen donate one electron to attain stable configuration.​​
They form monovalent cations.​	Forms monovalent H+ cation.
