case 5. diatomic molecules\nseveral common non - metal elements have basic units that are diatomic molecules. the name of the element refers to the diatomic molecule. for example, \hydrogen\ refers to h₂ and \oxygen\ refers to o₂. (if we mean the atom, we say atomic hydrogen or atomic oxygen). the common diatomic elements are the four halogens, oxygen, nitrogen, and hydrogen.\nexercise: list the names and formulas of the 7 elements that exist as diatomic molecules:\nexercise: write both the name and formulas (or symbols) of the gases in the following paragraph.\ndry air contains about 79% nitrogen and 21% oxygen, with small amounts of carbon dioxide, neon, and argon. polluted air may contain small amounts of sulfur dioxide, sulfur trioxide, nitrogen dioxide, dinitrogen monoxide, chlorine, ammonia, methane, and carbon monoxide.\nexercise: write the names of the compounds (or elements) in the following paragraph.\nprobably the most important element found uncombined in nature is o₂. o₂ is quite reactive, forming compounds with the halogens f₂, cl₂, br₂ and i₂. o₂ forms two compounds with h₂. following the usual rules of nomenclature, the most common oxide of hydrogen (h₂o) would be named dihydrogen monoxide. the other oxide of hydrogen is h₂o₂. o₂ forms a series of compounds with n₂, many of which are atmospheric pollutants, including no, n₂o, no₂, n₂o₄, n₂o₅.
