WebbThe first ionization energy is quantitatively expressed as X(g) + energy X + (g) + e −. where X is any atom or molecule, X + is the resultant ion when the original atom was stripped of a single electron, and e − is the removed electron. Ionization energy is positive for neutral atoms, meaning that the ionization is an endothermic process.

WebbIn general, ionization energy increases across a period and decreases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant. This pulls the electron cloud closer to the nucleus, strengthening the nuclear attraction to the outer-most electron, and is more difficult to remove (requires more energy).
