Pasangan unsur-unsur yang dapat membentuk ikatan kovalen adalah ...

jawaban yang tepat adalah A.

Ayo simak pembahasan berikut agar lebih paham.

Ikatan kovalen terbentuk karena adanya penggunaan pasangan elektron bersama oleh 2 atom berikatan. Senyawa membentuk ikatan untuk mencapai kestabilan oktet (elektron valensi berjumlah 8).

W : 2 4
X : 2 6
Y : 2 8 8
Z : 2 8 8 1

Ikatan kovalen dapat terjadi antara unsur W dengan X karena keduanya sama-sama cenderung menerima elektron (tidak ada atom yang melepas elektron). Sedangkan unsur Y sudah stabil dan unsur Z cenderung melepas elektron membentuk ion.
