MCQ
The third ionization energy is maximum for
- ANitrogen
- BPhosphorus
- CAluminium
- ✓Boron
✓
Answer
Correct option: D.
Boron
d
Boron has highest third ionization energy due to charge density and also after losing $3$ electrons boron attains noble gas configuration. Ionization energy decreases down the group.
