What should the IUPAC name for a binary covalent compound lack?

Binary covalent compounds are named with prefixes to show how many atoms of each element are present, and the second element’s name ends in -ide. Their names include the names of both nonmetals. Roman numerals are used in some ionic compound names to show a metal’s charge, so a binary covalent compound’s IUPAC name should lack Roman numerals.
