The value is not so low: 499 kJ/mol.
Potassium has a low ionization energy.
The ionization energy of aluminium is 5,985 77 eV. It is a medium energy.
An atom with high electron affinity is more likely to react with an atom that has low ionization energy. This is because low ionization energy indicates that the atom can easily lose an electron, making it more reactive and able to engage in bonding with an atom that has a strong attraction for electrons. Conversely, an atom with high ionization energy is less likely to readily lose electrons, making it less reactive in this context.
The fewer numbers of valence electrons, and the farther away those valence electrons are from the nucleus, the lower the ionization energy will be. So your group 1 and 2 metals toward the bottom of those groups will have low ionization energies, and therefore be very reactive.

low ionization energy
Sodium has a relatively low ionization energy, as it only requires a small amount of energy to remove an electron from a sodium atom. This is because sodium has one electron in its outermost shell, which makes it relatively easy to remove.
The electrons in actinium are disposed on seven energy levels.
no
Yes, nonmetals typically have a low first ionization energy compared to metals. This is because nonmetals have higher electronegativity and tend to gain electrons rather than lose them when forming ions, resulting in a lower energy requirement to remove an electron from a nonmetal atom.
Actinium has seven electron shells.
Potassium has a low ionization energy due to its large atomic size and one electron in its outermost shell, making it easier to remove that electron.
