Question

in the isoelectronic species calculate the ionic radii[ A°]of N-³,O-²,F-
​

Answer 1

Answer:

N

3−

,O

2−

and F

−

all have 10 electrons each. Thus they are iso electronic . For iso electronic species atomic size is inversely proportional to effective nuclear charge . Effective nuclear charge is inversely proportional to negative charge . N

3−

has maximum negative charge maximum atomic size . Similarly size of O 2− >F −
