Electronic configuration of element X (Atomic number 16) is 2, 8, 6 and that of element Y (Atomic number 16) is 2, 8, 7. Element Y requires only one electron to complete the octet but X requires 2 electrons. So, Y will be more reactive.

Element Y with atomic number 17 (which is chlorine) will be more chemically reactive than element X with atomic number 16 (which is sulfur).

The reactivity of an element is determined by its ability to gain or lose electrons. Chlorine, with atomic number 17, has one more electron in its outermost shell compared to sulfur with atomic number 16. This extra electron in chlorine makes it more likely to gain an electron and form a stable electron configuration, which increases its reactivity.

Therefore, the correct answer is: b) Element Y with atomic number 17 (chlorine) will be more chemically reactive than element X with atomic number 16 (sulfur).
