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

Answer: (C)

$_{6}C \to_{32}Ge$ - Atomic radii increases.

Answer 2

$e^{\ell}$ 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.
