The ionic radius of the fluoride ion is:
- A
72 pm
- B
95 pm
- C
136 pm
- D
157 pm
The atomic radius of fluorine is 72pm, but when an electron is added, the affective nuclear charge decreases so the ionic radius of an anion is always greater than the atomic radius for fluoride, it is 136pm.
Key point: fluoride is the anion of fluorine.
The radius of fluorine atom is 72pm.
The radius of Na is 157pm and the radius of Na+ is 95pm.
