Answer
Both A and R are true but R is not the correct explanation of A.
Explanation — Hydrogen is a non-metal which also forms positive ions by losing its electron like metals. Hence, assertion (A) is true.
Metals are defined as the elements which form positive ions by the loss of electrons. Hence, reason (R) is true.
However, reason (R) does not explain how hydrogen form positive ion. Hence, reason (R) is not correct explanation of assertion (A).
