In general, the property (magnitudes only) that shows an opposite trend in comparison to other properties across a period is :

Options

  1. Alonization enthalpy
  2. BElectronegativity
  3. CElectron gain enthalpy
  4. DAtomic radius

Correct answer

D. Atomic radius

Step-by-step solution

On moving Left to Right along a period. Atomic Radius ⇒⇒ decreases. Electronegativity ⇒⇒Increases. Electron gainenthalpy ⇒⇒ Increases. Ionisation Enthalpy ⇒⇒ Increases.
