alleryAmong isoelectronic species, a larger nuclear charge gives a radius:
ADoubled
BSmaller
CLarger
DEqual
Answer & Solution
Correct answer: B. Smaller
1. All the species hold the same number of electrons.
2. A stronger nucleus pulls those electrons in harder.
3. So the larger positive charge gives the smaller radius.
