Verified step by step guidance1
Identify the elements present in the molecular formula NO_2: nitrogen (N) and oxygen (O).
Recognize that this is a molecular compound composed of nonmetals, so the naming follows the rules for covalent compounds.
Use prefixes to indicate the number of atoms of each element: 'mono-' for one and 'di-' for two. Since there is one nitrogen atom, the prefix 'mono-' is often omitted for the first element.
Name the first element (nitrogen) followed by the second element (oxygen) with the suffix '-ide' to indicate it is an anion or part of a compound, and use the appropriate prefix for the number of oxygen atoms, which is 'di-'.
Combine these parts to form the name: 'Nitrogen dioxide'.
