As an example potassium has a lower first ionization energy than aluminum (Al).
The ionization energy of aluminium is 5,985 77 eV. It is a medium energy.
Boron has the greatest ionization energy among aluminum, boron, and carbon. This is because boron has a lower atomic size compared to aluminum and carbon, leading to increased electronegativity and stronger attraction for electrons in the atomic structure.
Among lead, copper, zinc, and aluminum, aluminum has the highest ionization tendency because it requires the least amount of energy to remove an electron due to its low atomic size and high nuclear charge.
Aluminum has a lower first ionization energy compared to its neighbors, magnesium and silicon, indicating that it is less metallic than magnesium but more metallic than silicon. This suggests that aluminum exhibits intermediate metallic character within its group on the periodic table.
