Ionic Radius Vs Atomic Radius
Mediumchemistry
Which statement is correct regarding ionic vs atomic radius?
Select the correct option:
Solution
Incorrect! Answer:
For same element cation < atom < anion
- Cation Formation: Losing an electron increases the effective nuclear charge felt by remaining electrons and sometimes removes a whole valence shell. Result: Cation < Neutral Atom.
- Anion Formation: Adding an electron increases electron-electron repulsion, forcing the electron cloud to expand. Effective nuclear charge per electron decreases. Result: Anion > Neutral Atom.
- Combined Order: For a given element (e.g., Iodine), the size comparison is: Anion (I−) > Neutral (I) > Cation (I+).
