Monatomic gas | Atomic Structure, Kinetic Theory Gases - Britannica Monatomic gas, gas composed of particles (molecules) that consist of single atoms, such as helium or sodium vapour, and in this way different from diatomic, triatomic, or, in general, polyatomic gases
What are Monatomic Gases? - BYJUS Monatomic compounds are made of a single atom, whereas diatomic compounds are made of molecules with two atoms This is the primary distinction between monatomic and diatomic compounds
In Chemistry, what is Monatomic? (with pictures) - AllTheScience In chemistry, the term "monatomic" often refers to a state when elements occur in the form of single atoms that are not bound to other atoms This occurs mostly with gases, and all elements can achieve this single-atom state at sufficiently high temperatures
