**आरगॉन** (Ar) (अणुक्रमांक १८) हा एक अधातू असून अर्गोन हे रासायनिक घटक आहे. त्याचा अणू क्रमांक १८ आहे. हे मूलद्रव्य आवर्तसारणीमध्ये शेवटच्या म्हणजे १८  व्या गणात आहे. पृथ्वीच्या वातावरणातील अर्गोन हे 0.934% (9340 पीपीएमव्ही) वर तिस-या क्रमांकाचा प्रचलित वायू आहे. पाणी वाष्प (जे सुमारे ४००० पीपीएमव्ही सरासरी असते परंतु मोठ्या प्रमाणात बदलते), कार्बन डाय ऑक्साईड (४०० पीपीएमव्ही) जितके विपुल प्रमाणात आणि बहुतेक वेळा निऑन (१८ पीपीएमव्ही) म्हणून ५०० पट अधिक म्हणून भरपूर प्रमाणात होते. पृथ्वीच्या क्रॉस्टमध्ये आरगॉन हे सर्वात प्रचलित असलेला वायू आहे, ज्यामध्ये 0.00015% पेंढा आहे. हा एक निष्क्रीय वायू किंवा उदासीन वायू आहे.
