MCQ
The second ionization potential is
- ALess than the first ionization potential
- BEqual to the first ionization potential
- ✓Greater than the first ionization potential
- DNone of these
✓
Answer
Correct option: C.
Greater than the first ionization potential
c
(c) Greater than the first ionization energy because after removal one ${e^ - }$, effective nuclear charge increases.
(c) Greater than the first ionization energy because after removal one ${e^ - }$, effective nuclear charge increases.
