उत्तर
Both A and R are true but R is not the correct explanation of A.
Explanation:
Hydrogen is placed in group 1 and can gain an electron to attain a helium-like configuration, so both statements are true. Its group 1 placement is associated with its single valence electron and ability to lose it, not with gaining an electron.
