Assertion (A) : Hydrogen is extremely small in size as compared to the normal atomic and ionic sizes of 50 to 200 pm. As a consequence,
does not exist freely and is always associated with other atoms or molecules.
Reason (R) : It has unique behaviour and, therefore, best placed separately in the Periodic Table.
