Dinitrogen pentoxide


The name of a binary covalent compound such as this is found by simply putting Greek prefixes in front of each element, excluding "mono-" for the first element only, and listing it in order of how the elements appear in the compound.

"Di-" is the prefix for #2#, and "penta-" is the prefix for #5# (for oxygen, the final "a" is often excluded in the prefixes), thus, the name is dinitrogen pentoxide.
