Ionization energy is more commonly used to remove the topmost electron in the atom very important information if you are getting ready for a test.
The first ionization energy is 1681 kJ/mol.
The first ionization energy for carbon is 1 086,5 kJ/mol. The first ionization energy for oxygen is 1 319,9 kJ/mol.
Across a row on the periodic table ionization energy increases. Down a column, ionization energy decreases. --------------------------------------------------------- The first Ionization energy of Boron is 800.6 kJ mol-1
As an example potassium has a lower first ionization energy than aluminum (Al).
Barium has more energy levels. So it has lesser ionization energy.
Sodium's first ionization energy is 495 kJ / mol.

Fluorine has the largest first ionization energy among the halogens.
Fluorine has the largest first ionization energy among the halogens.
Helium has the highest ionization energy.
The first ionization energy is 1681 kJ/mol.
The first ionization energy for carbon is 1 086,5 kJ/mol. The first ionization energy for oxygen is 1 319,9 kJ/mol.
When electronegativity decrease the first ionization energy also decrease.
The ionization energy (first) of einsteinium is 619 kJ/mol.
The first ionization energy of germanium is 7.9 electron volts (eV).
The first ionization energy of neon is higher: 2 080,7 kJ/mol.
The estimated first ionization energy of rutherfordium is 579,9 kJ/mol.
