Question

which of the following is a correct guideline when writing the iupac chemical name of a binary compound from a chemical formula? binary compounds generally end with an -ite. roman numerals are used to indicate the number of each atom in the formula. the metal anion is named first, followed by the non - metal cation. binary ionic compounds are always named using the positive ion followed by the negative ion.

Explanation:

Binary ionic compounds follow the naming convention of positive ion (cation) first and negative ion (anion) second. Binary compounds don't generally end with -ite. Prefixes (not Roman numerals) are used to indicate number of atoms in covalent binary compounds. In naming, metal cation is named first, not anion, followed by non - metal anion.

Answer:

Binary ionic compounds are always named using the positive ion followed by the negative ion.
