Question

Which of the following series correctly represents relations between the elements from X to Y?
\(X\to Y\)

• A. \(_{3}Li \to_{19}K\) - Ionization enthalpy increases.
• B. \(_{9}F\to_{35}Br\) - Electron gain enthalpy with negative sign increases.
• C. \(_{6}C \to_{32}Ge\) - Atomic radii increases.
• D. \(_{18}Ar\to_{54}Xe\) - Noble character increases.

Answer 1

The Correct Option is C

$e^{\ell}$ on moving down the gsaap shell number increases so its radii also increase from "C to Ge".

So, the correct option is (C): \(_{6}C \to_{32}Ge\) - Atomic radii increases.
