Web13 Nov 2024 · The energy required to remove the lowest orbiting electron from the influence of the central protons is the ionization energy. Danish physicist Niels Bohr first calculated this energy for hydrogen in 1913, for which he won the Nobel Prize. Determine what atom you want to use for calculating the ionization energy. WebConsider potassium. The second ionization energy is significantly higher, as it involves the removal of a core electron from an ion with a noble gas configuration. Similarly, for calcium, there is a high increase from the second to third ionization energy as a core electron is removed from a cation with a noble gas configuration.

WebIonization energy generally decreases down a group. Explanation: Ionization energy is the energy needed to remove one electron from an atom in the gaseous state. This electron would be a valence electron, or an electron in the outermost energy level/shell, because they're the easiest to remove.
