Mayroon din itong atomikong timbang na 20.183, punto ng pagkatunaw (MP o melting point) na 248.67 °C, punto ng pagkulo (BP o boiling point) na 245.95 °C, at V na 0.[13] Bagaman isang napakakaraniwang elemento sa uniberso, bihira ito sa mundo. Isa itong hindi magalaw, walang-kulay, at hindi nakikitang gas sa pamantayang mga kalagayan o kundisyon. Nagbibigay ang neon ng kakaiba at natatanging mamula-mula o naranghalang katingkaran kapag dinaanan ng kuryente[13] at kapag ginamit sa tubong Geissler o tubong pangdiskarga at mga lamparang neon (ilawang neon).[14][15] pangkalakalan (commercial) na nakukuha ito mula sa hangin, kung saan natatagpuan ito sa maliliit o bakas na mga bilang. Ginagamit ito para sa mga ilaw ng neon ng lungsod.[13] Nagmula ang salitang neon sa salitang Griyegong nangangahulugang "bago". Natuklasan ito nina William Ramsay (binabaybay ding William Ramsey[13]) at Morris W. Travers noong 1898.[13]

Hindi ito nagkakaroon ng reaksiyon at hindi sumasanib sa iba pang mga elemento,[13] kaya't matatagpuan nag-iisa o nagsasarili lamang. Bagaman may katangiang maging mapula o narangha kapag dinaanan ng kuryente, umiilaw o nagliliwanag rin ito na may iba't ibang mga kulay. Dahil sa kalidad o katangiang ito ng neon, kaya ito ginagamit sa mga karatula.
