Want this question answered?
Potassium has a low ionization energy.
The ionization energy of aluminium is 5,985 77 eV. It is a medium energy.
The value is not so low: 499 kJ/mol.
ionization potential energy. but remember the atom must be neutral .
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.
