Isotopes of neon explained

Neon (₁₀Ne) possesses three stable isotopes:,, and . In addition, 17 radioactive isotopes have been discovered, ranging from to, all short-lived. The longest-lived is with a half-life of . All others are under a minute, most under a second. The least stable is with a half-life of . See isotopes of carbon for notes about the measurement. Light radioactive neon isotopes usually decay to fluorine or oxygen, while heavier ones decay to sodium.
