Question

why do alkali metals possess minimum ionisation energy
long 2 marker answer ​

Answer 1

Answer:

$\huge\colorbox{pink}{αηѕωєя}$

Alkali metals have the lowest ionization energy in each period and this is because they are having the largest atomic size in their respective period. The valence electron in large size atoms are held loosely by the nucleus and can be lost easily.

Answer 2

$\huge\underline\color{green}{Answer}$

Alkali metals belong to the s-block elements occupying the leftmost side of the periodic table. Alkali metals readily lose electrons, making them count among the most reactive elements on earth. In this article, we will explain the electronic configurations, ionization enthalpy, hydration enthalpy and atomic, ionic radii and other physical and chemical properties of the group one alkali metals.
