Neon (griechisch νέος néos, deutsch ‚neu‘) ist ein chemisches Element mit dem Symbol Ne und der Ordnungszahl 10. Im Periodensystem steht es in der 8. Hauptgruppe, bzw. der 18. IUPAC-Gruppe und zählt daher zu den Edelgasen. Wie die anderen Edelgase ist es ein farbloses, äußerst reaktionsträges, einatomiges Gas. In vielen Eigenschaften wie Schmelz- und Siedepunkt oder Dichte steht es zwischen dem leichteren Helium und dem schwereren Argon. Im Universum gehört Neon zu den häufigsten Elementen, auf der Erde ist es dagegen relativ selten, da wie bei Helium ein großer Teil des Gases in das Weltall entwichen ist. Vorwiegend ist es in der Erdatmosphäre zu finden, nur geringe Mengen sind in Gesteinen eingeschlossen. Wie Krypton und Xenon wurde auch Neon 1898 von William Ramsay und Morris William Travers durch fraktionierte Destillation von flüssiger Luft entdeckt. Die bekannteste Anwendung sind die Leuchtröhren mit Neonfüllung (Neonlampen), in denen Neon durch Gasentladungen in einer typischen orangeroten Farbe zum Leuchten angeregt wird.
