Question

there are four common oxoanions of iodine and two common oxoanions of nitrogen. match the name of each ion to its formula. io₄⁻ io₃⁻ io₂⁻ io⁻ no₃⁻ no₂⁻ answer bank nitrate ion nitrite ion hypoiodite ion periodate ion iodite ion nitride ion iodate ion iodide ion

Explanation:

The periodate ion has the formula $IO_{4}^{-}$. The iodate ion has the formula $IO_{3}^{-}$. The iodite ion has the formula $IO_{2}^{-}$. The hypoiodite ion has the formula $IO^{-}$. The nitrate ion has the formula $NO_{3}^{-}$. The nitrite ion has the formula $NO_{2}^{-}$. These are based on the standard naming conventions for oxo - anions in chemistry where the number of oxygen atoms in the anion determines the prefix (hypo - for least oxygen, per - for most oxygen) and the suffix (-ite for less oxygen, -ate for more oxygen).

Answer:

$IO_{4}^{-}$: periodate ion
$IO_{3}^{-}$: iodate ion
$IO_{2}^{-}$: iodite ion
$IO^{-}$: hypoiodite ion
$NO_{3}^{-}$: nitrate ion
$NO_{2}^{-}$: nitrite ion
