In general, the properties that decrease and increase down a group in the periodic table, respectively, are :
Options
- AAtomic radius and electronegativity
- BElectronegativity and atomic radius
- CElectronegativity and electron gain enthalpy
- DElectron gain enthalpy and electronegativity
Correct answer
B. Electronegativity and atomic radius
Step-by-step solution
(i) Electronegativity: Top to bottom decrease.
(ii) Atomic Radius: generally Increases top to Bottom.
(iii) Electron affinity: generally top to bottom decreases.
(ii) Atomic Radius: generally Increases top to Bottom.
(iii) Electron affinity: generally top to bottom decreases.
