moleculescommonly

The term "molecules commonly" is not a standard scientific or chemical term. It is likely a misspelling or an incomplete phrase. If it refers to molecules that are frequently encountered in everyday life or in specific scientific contexts, the list would be extensive and depend heavily on the scope. For instance, common molecules in biology include water (H2O), carbon dioxide (CO2), and glucose (C6H12O6). In materials science, common molecules might include polymers like polyethylene or smaller molecules like benzene. In the atmosphere, common molecules are nitrogen (N2), oxygen (O2), and argon (Ar).

If "molecules commonly" was intended to be a search query, it is too broad to yield specific results without further context. To discuss common molecules, one would typically specify a field, such as "common molecules in the human body," "common molecules in Earth's atmosphere," or "common molecules found in cooking." Each of these would lead to a distinct and manageable set of examples. Without additional information or clarification, the phrase "molecules commonly" remains ambiguous and does not represent a defined concept in chemistry or related disciplines. Further context is needed to provide a meaningful explanation.
