Potassium
Fluorine has the largest first ionization energy among the halogens.
Sodium
As an example potassium has a lower first ionization energy than aluminum (Al).
Francium in group 1 has the lowest first ionization energy.
The ionization energy of fluorine is 1681 kJ/mol (the first) and the ionization energy of iodine is 1008,4 kJ/mol.
Helium has the highest ionization energy.
Fluorine has the largest first ionization energy among the halogens.
Na, sodium
Potassium has a higher ionization energy than cesium.
As an example potassium has a lower first ionization energy than aluminum (Al).
Sodium
As an example potassium has a lower first ionization energy than aluminum (Al).
Ionization energy decrease down the group.So in halogens,Fluorine has highest 1st ionization energy.
xenon increases from left to right across periods (first ionization energy)
T he smallest first ionization energyis for lithium.
Halogens, specially fluorine
Francium in group 1 has the lowest first ionization energy.
