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.
Low
Potassium has a low ionization energy.
high
Low ionization energies are typically characteristic of atoms that have large atomic size and few protons in their nucleus, such as alkali metals and alkaline earth metals. These atoms have loosely bound electrons that require less energy to remove.
The ionization energy of aluminium is 5,985 77 eV. It is a medium energy.
The ionization energy tells us about the energy required (and thus the ease) with which an atom/ion can give away an electron (in the outermost shell). So, atoms with low ionization energies ( lowest for Caesium) give away the electron with ease

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.
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.
