potassium K
The first ionization energy of an element, like sulfur (s), is important in determining its reactivity. A low first ionization energy means it is easier for the element to lose an electron and form a positive ion, making it more reactive. Conversely, a high first ionization energy means it is harder for the element to lose an electron, making it less reactive.
Fluorine has the largest first ionization energy among the halogens.
Sodium (Na) has the lowest first ionization energy in period 3.
The first level ionization energy oif aluminium is 577,5 kJ/mol.All alkali metals have lower values for the ionization energy.
The element that has a lower first ionization energy than aluminum (Al) is magnesium (Mg). Magnesium is one period above aluminum on the periodic table, and as you move down a group or family, the ionization energy tends to decrease.
Element P (phosphorus) has a lower first ionization energy than element S (sulfur).
Helium has the highest ionization energy.

Fluorine has the largest first ionization energy among the halogens.
Sodium (Na) has the lowest first ionization energy in period 3.
As an example potassium has a lower first ionization energy than aluminum (Al).
The first level ionization energy oif aluminium is 577,5 kJ/mol.All alkali metals have lower values for the ionization energy.
T he smallest first ionization energyis for lithium.
Halogens, specially fluorine
The element that has a lower first ionization energy than aluminum (Al) is magnesium (Mg). Magnesium is one period above aluminum on the periodic table, and as you move down a group or family, the ionization energy tends to decrease.
The element with the largest first ionization energy is (a) Sb (antimony). It has the highest first ionization energy among the elements listed.
