Verified step by step guidance1
Identify the elements present in the compound P3N5: phosphorus (P) and nitrogen (N).
Determine the number of atoms of each element from the formula: 3 phosphorus atoms and 5 nitrogen atoms.
Use the appropriate prefixes to indicate the number of atoms: 'tri-' for 3 and 'penta-' for 5.
Name the first element (phosphorus) with its full element name and the second element (nitrogen) with the suffix '-nitride' to indicate it is combined with a more electropositive element.
Combine the prefixes and element names to form the correct chemical name: 'Triphosphorus pentanitride'.
