Number of Neutrons in Neon
How many neutrons are there in Neon?
From 10 to 12.
The chemical element Neon has three natural isotopes, and all of them are stable (not radioactive): neon-20, with 10 neutrons, neon-21, with 11 neutrons and neon-22, with 12 neutrons. Neon-20 is the most abundant of them (90.5%), followed by neon-22 (9.2%) and neon-21 (0.3%) (source: “Nature’s Building Blocks: an A-Z Guide to the Elements”).
