Q. The first ionization potential (IP) of the elements $Na , Mg , Si , P , Cl$ and $Ar$ are $5.14,7.65,8.15$ $10.49,12.97$ and $15.76 eV$, respectively. The IP (in eV) of $K$ is closest to :

KVPYKVPY 2020

Solution:

The first ionisation potential of $K$ is less than $Na$
$\therefore $ The first ionization potential of $K$ is closest to $4.3$
