Answer 2

Answer:

(D) Q and S

Explanation:

The atomic numbers of the given four elements P, Q, R and S, respectively, are 6, 8, 10, and 12. Q (8= 2,6) and S (12 = 2,8,2) are the two elements that can react to produce ionic bonds (or ionic compounds). As a result, S transfers two electrons to Q to complete their octet.

Therefore the correct answer to the given question is an option (D) Q and S
