MCQ
The ionization potential of sodium is $5.48\, eV.$ The $I.P.$ of potassium is ............. $\mathrm{eV}$
- AEqual to that of sodium
- B$5.68$
- ✓$4.68$
- D$10.88$
✓
Answer
Correct option: C.
$4.68$
c
The Ionization potential decreases as we move down the group in peeiodic table. This is due to increase in atomic size that reduces attraction force between the nucleus and valance electrons. Moreover, Shielding or Screening effect plays important role to affect lonization potential.
