Elements in the same group of the periodic table often form oxyanions with the same general formula. The anions are also named in a similar fashion. Based on these observations, suggest a chemical formula or name, as appropriate, for each of the following ions: (d) hydrogen tellurate ion.

Verified step by step guidance
1
Identify the group in the periodic table where tellurium is located. Tellurium is in Group 16, also known as the chalcogens.
Recognize that elements in Group 16 form oxyanions with similar formulas. For example, sulfur forms sulfate \( \text{SO}_4^{2-} \) and selenium forms selenate \( \text{SeO}_4^{2-} \).
Understand that the tellurate ion would have a similar structure to sulfate and selenate, likely \( \text{TeO}_4^{2-} \).
Consider the addition of hydrogen to the tellurate ion. Adding one hydrogen ion \( \text{H}^+ \) to \( \text{TeO}_4^{2-} \) would result in the hydrogen tellurate ion \( \text{HTeO}_4^- \).
Conclude that the chemical formula for the hydrogen tellurate ion is \( \text{HTeO}_4^- \), following the pattern of naming and formula structure for oxyanions in Group 16.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Oxyanions

Oxyanions are negatively charged ions that contain oxygen and another element. They typically form when an element from the periodic table combines with oxygen, resulting in a polyatomic ion. The naming convention for oxyanions often depends on the number of oxygen atoms present, with suffixes like '-ate' and '-ite' indicating different oxidation states.

Periodic Table Groups

Elements in the same group of the periodic table share similar chemical properties due to their similar valence electron configurations. This similarity often extends to the types of ions they form, including oxyanions. Understanding the group trends helps predict the behavior and formulas of compounds formed by these elements.

Hydrogen Ions in Oxyanions

When hydrogen is included in an oxyanion, it typically indicates the presence of a hydrogen atom bonded to the anion. This can alter the charge and naming of the oxyanion. For example, the hydrogen tellurate ion would be derived from the tellurate ion by adding a hydrogen atom, resulting in a specific formula and name that reflects this addition.

Textbook Question

Carbonic acid occurs in carbonated beverages. When allowed to react with lithium hydroxide, it produces lithium carbonate. Lithium carbonate is used to treat depression and bipolar disorder. Write chemical formula for carbonic acid, lithium hydroxide, and lithium carbonate.

Textbook Question

Cyclopropane is an interesting hydrocarbon. Instead of having three carbons in a row, the three carbons form a ring, as shown in this perspective drawing (see Figure 2.18 for a prior example of this kind of drawing):

Cyclopropane was at one time used as an anesthetic, but its use was discontinued, in part because it is highly flammable. (b) The three carbon atoms are necessarily in a plane. What do the different wedges mean?
