Which of the following is not correct with the property mentioned against them?
Show Hint
- I$^-$>I>I$^+$ : radius
- Li>Be>B : first ionization enthalpy
- Cl>S>P : electronegativity
- Rb>K>Na : screening effect
The Correct Option is B
Solution and Explanation
Although Be has a filled s-subshell (stable), its ionization enthalpy is higher than B.
Hence, the statement “Li>Be>B” is incorrect. The correct order is: Li<B<Be.
