Verified step by step guidance

Step 1: Understand the structure of the polyatomic ion IO3–. This ion consists of iodine (I) and three oxygen atoms (O), with an overall negative charge.

Step 2: Recognize the naming convention for polyatomic ions containing oxygen. These are often named based on the number of oxygen atoms and the oxidation state of the central atom.

Step 3: Recall that the suffix '-ate' is typically used for the most common or typical oxyanion of an element. In this case, IO3– is the most common oxyanion of iodine.

Step 4: Compare the given options: 'iodite', 'hypoiodate', 'iodide', 'iodate', and 'periodate'. Note that 'iodate' is the correct name for IO3–, as it follows the standard naming convention for oxyanions.

Step 5: Understand that 'iodite' would refer to a less oxidized form (IO2–), 'hypoiodate' would refer to an even less oxidized form (IO–), 'iodide' is simply the iodide ion (I–), and 'periodate' refers to a more oxidized form (IO4–).
