Verified step by step guidance1
Identify the two elements in the compound: here, \( N_2 O_5 \) consists of nitrogen (N) and oxygen (O).
Determine the number of atoms of each element using the subscripts: there are 2 nitrogen atoms and 5 oxygen atoms.
Use prefixes to indicate the number of atoms for each element. The prefix for 2 is 'di-' and for 5 is 'penta-'.
Name the first element (nitrogen) with its prefix, so it becomes 'dinitrogen'. For the second element (oxygen), use the prefix and change the ending to '-ide', resulting in 'pentoxide'.
Combine the names to form the full name: 'dinitrogen pentoxide'. This follows the rules for naming binary molecular compounds.
