Explanation:

1. For an element to form a stable compound with 2 H atoms and satisfy the octet rule, it needs 2 more valence electrons to reach 8.

• F, Cl: Have 7 valence electrons, need 1 H atom (forms HF, HCl).
• P, N: Have 5 valence electrons, need 3 H atoms (forms PH₃, NH₃).
• O, S: Have 6 valence electrons, need 2 H atoms (forms H₂O, H₂S), where each achieves a full octet.

Answer:

O. O, S. S
