Out of $Li$ and $K$,which will have stronger metallic character and why?

(B) Potassium $(K)$ has a stronger metallic character than lithium $(Li)$.
This is because metallic character depends on the ease with which an atom can lose its valence electrons.
As we move down a group in the periodic table,the atomic size increases due to the addition of new shells.
Consequently,the valence electrons are further away from the nucleus and are held less tightly by the nuclear charge.
Therefore,$K$ can lose its valence electron more easily than $Li$,making it more metallic.
