JEE Mains · Chemistry · STD 11 - 3. Classification of elements and periodicity in properties
In general, the property (magnitudes only) that shows an opposite trend in comparison to other properties across a period is
- A Electronegativity
- B Electron gain enthalpy
- C Ionization enthalpy
- D Atomic radius
Answer & Solution
Correct Answer
(D) Atomic radius
Step-by-step Solution
Detailed explanation
In general across a period atomic radius decreases while ionisation enthalpy, electron gain enthalpy and electronegativity increases because effective nuclear charge \(\left(Z_{\text {eff }}\right)\) increases.
