MCQ
Atom with ____atomic radii and ___ionisation potential tends to gain electrons:
- ALarge, high
- BLarge, low
- CSmall, low
- DSmall, high
✓
Answer
- Small, high
Explanation:
Ionization energies increase moving from left to right across a period (decreasing atomic radius).
So, atom with small atomic radii and high ionisation potential tends to gain electrons.
