Question

Elements in the same family often form oxyanions of the same general formula. The anions are named in a similar fashion. What are the names of the oxyanions of selenium and tellurium: $\mathrm{SeO}_{4}^{2-}, \mathrm{SeO}_{3}{ }^{2-}, \mathrm{TeO}_{4}{ }^{2-}, \mathrm{TeO}_{3}^{2-} ?$

Step 1

For an element X, the oxyanion with more oxygen atoms is named "X-ate" (e.g., sulfate for SO₄²⁻), while the one with fewer oxygen atoms is named "X-ite" (e.g., sulfite for SO₃²⁻). Now, let's apply this convention to the given oxyanions: Show more…

Key Concepts

Oxyanion Nomenclature

This concept involves the systematic rules used to name polyatomic ions that contain oxygen. Typically, the suffix '-ate' is used for oxyanions with the highest number of oxygen atoms, while '-ite' is used for those with fewer oxygen atoms. Understanding these naming conventions is essential in chemistry for consistently identifying and communicating the structure and composition of various oxyanions.

Periodic Trends and Homologous Series

Elements in the same group of the periodic table often exhibit similar chemical properties, including the formation of analogous compounds. Recognizing this pattern, especially among chalcogens, aids in predicting the types of oxyanions that can form. These similarities allow chemists to deduce naming patterns and chemical behaviors based on group trends rather than memorizing each individual case.
