Explanation:<\/strong><\/h3>\n\n\n\n

When forming ionic compounds, cations and anions combine in ratios that result in overall electrical neutrality. In this case, sodium ion (Na\u207a) is a monovalent cation, meaning it carries a single positive charge. It can combine with any monovalent anion, such as the oxyanions of iodine, which also carry a single negative charge (\u207b1). Because the charges are equal and opposite, these ions combine in a 1:1 ratio, resulting in empirical formulas of the form NaIO\u2093<\/strong>, where x depends on the number of oxygen atoms in the polyatomic ion.<\/p>\n\n\n\n

The iodine oxyanions are named systematically based on the number of oxygen atoms bonded to the iodine atom:<\/p>\n\n\n\n

    \n
  • IO\u207b<\/strong> is called hypoiodite<\/em>. The prefix \u201chypo-\u201d and suffix \u201c-ite\u201d indicate fewer oxygen atoms than the \u201c-ite\u201d form.<\/li>\n\n\n\n
  • IO\u2082\u207b<\/strong> is iodite<\/em>, the \u201c-ite\u201d form with fewer oxygens than \u201c-ate\u201d.<\/li>\n\n\n\n
  • IO\u2083\u207b<\/strong> is iodate<\/em>, the common \u201c-ate\u201d form.<\/li>\n\n\n\n
  • IO\u2084\u207b<\/strong> is periodate<\/em>, using the prefix \u201cper-\u201d and suffix \u201c-ate\u201d to denote the most oxygen-rich form.<\/li>\n<\/ul>\n\n\n\n

    When these anions combine with Na\u207a, their names are prefixed by \u201csodium\u201d (the cation name), and the empirical formula reflects the 1:1 stoichiometry. These naming conventions are standard for ionic compounds involving polyatomic ions and help ensure consistent communication in chemistry.<\/p>\n\n\n\n
