# Isotopen van neon

Het chemisch element neon (Ne), met een atoommassa van 20,1797(6) u, bezit 3 stabiele isotopen: $^{20}$Ne, $^{21}$Ne en $^{22}$Ne, waarvan de eerste het meest abundant is (ongeveer 90%). De overige 16 radio-isotopen zijn onstabiel en hebben een relatief korte halveringstijd.
De kortstlevende radio-isotoop van neon is $^{16}$Ne, met een halfwaardetijd van amper 9 × 10$^{−21}$ s. De langstlevende is $^{24}$Ne, met een halfwaardetijd van 3,38 minuten. Vrijwel alle andere isotopen vervallen binnen de seconde.
