Question

Consider the following values of I.E.(eV) for elements W and X : Element W: I.E.1=10.5, I.E.2=15.5, I.E.3=24.9, I.E.4=79.8. Element X: I.E.1=8, I.E.2=14.8, I.E.3=78.9, I.E.4=105.8. Other two element Y and Z have outer electronic configuration ns2 np4 and ns2 np5 respectively. Then according to given information which of the following compound(s) is/are not possible?

Correct answer: B,C. Step 1: Recall that representative elements comprise s-block and p-block elements (excluding noble gases). Step 2: Tellurium (Group 16), Thallium (Group 13), and Astatine (Group 17) are p-block representative elements. Tantalum (Z=73) is a d-block transition element. Step 3: Therefore, Tantalum is not a representative element, corresponding to option (b).
