Guida verificata passo dopo passo1
Identify the elements in the compound: N (nitrogen) and O (oxygen).
Determine the number of atoms of each element from the formula N_2O_5: there are 2 nitrogen atoms and 5 oxygen atoms.
Use the appropriate prefixes for the number of atoms: 'di-' for 2 and 'penta-' for 5.
Name the first element (nitrogen) with its prefix: 'dinitrogen'.
Name the second element (oxygen) with its prefix and change the ending to '-ide': 'pentoxide'. Combine to get 'dinitrogen pentoxide'.
