Solution Steps

Step 1: Identify the Oxoanions of Iodine

The oxoanions of iodine are:

  • Periodate ion
  • Iodate ion
  • Iodite ion
  • Hypoiodite ion
Step 2: Match Iodine Oxoanions to Their Formulas
  • Periodate ion: This is the ion with the most oxygen atoms, which is \(\mathrm{IO}_{4}^{-}\).
  • Iodate ion: This is the ion with one less oxygen than periodate, which is \(\mathrm{IO}_{3}^{-}\).
  • Iodite ion: This is the ion with one less oxygen than iodate, which is \(\mathrm{IO}_{2}^{-}\).
  • Hypoiodite ion: This is the ion with the least oxygen, which is \(\mathrm{IO}^{-}\).
Step 3: Identify the Oxoanions of Nitrogen

The oxoanions of nitrogen are:

  • Nitrate ion
  • Nitrite ion
Step 4: Match Nitrogen Oxoanions to Their Formulas
  • Nitrate ion: This is the ion with more oxygen atoms, which is \(\mathrm{NO}_{3}^{-}\).
  • Nitrite ion: This is the ion with fewer oxygen atoms, which is \(\mathrm{NO}_{2}^{-}\).

Final Answer

  • \(\mathrm{IO}_{4}^{-}\): \(\boxed{\text{Periodate ion}}\)
  • \(\mathrm{NO}_{3}^{-}\): \(\boxed{\text{Nitrate ion}}\)
  • \(\mathrm{IO}_{3}^{-}\): \(\boxed{\text{Iodate ion}}\)
  • \(\mathrm{IO}_{2}^{-}\): \(\boxed{\text{Iodite ion}}\)
  • \(\mathrm{NO}_{2}^{-}\): \(\boxed{\text{Nitrite ion}}\)
  • \(\mathrm{IO}^{-}\): \(\boxed{\text{Hypoiodite ion}}\)
