Consequently, the process is highly endothermic, requiring a significant input of energy to overcome the natural electrostatic repulsion between the added electron and the existing electron cloud. Unlike alkali metals, which have highly negative electron affinities and readily accept electrons, neon presents a formidable challenge to incoming electrons.

Neon, with an atomic number of 10, has an electron configuration of 1s² 2s² 2p⁶. In mass spectrometry, the ionization energy and electron affinity values are critical for determining the mass-to-charge ratio of neon ions.
For most elements, this process is exothermic, releasing energy as the atom achieves a more stable, lower-energy configuration. Because neon possesses a complete octet in its valence shell, adding an extra electron forces that electron into a new, higher-energy energy level.

Conversely, neon sits at the peak of this stability curve for its period. This value confirms the theoretical models of atomic structure and validates the octet rule.
