What Are the Oxidation States of Group 16 Elements?

TL;DR

Group 16 elements can display both negative and positive oxidation states. Oxygen typically has an oxidation state of -2 but can also exist as 0 or -1 in certain compounds. Sulfur mainly shows -2, along with possible states of +2 and +4, while other group members like selenium and tellurium vary between -2 and +6.

Questions & Answers

Q: What are the possible oxidation states of oxygen?

Oxygen typically has a common oxidation state of -2 in compounds, but can have an oxidation state of 0 or -1 in specific molecules such as oxide and water, respectively.

Q: What are the oxidation states of sulfur?

Sulfur commonly has an oxidation state of -2, similar to oxygen, but it can also exhibit oxidation states of +2 and +4 in compounds like hydrogen sulfide and sulfur dioxide.

Q: Why does oxygen have a negative oxidation state?

Oxygen is highly electronegative, meaning it has a strong tendency to gain electrons. As a result, oxygen often has a negative oxidation state in compounds.

Q: Can oxygen have a positive oxidation state?

Yes, in certain molecules where oxygen is less electronegative than other elements, it can have a positive oxidation state. For example, in the compound OF2, oxygen has an oxidation state of +2.

Q: What are the oxidation states of selenium and tellurium?

Selenium can exhibit oxidation states of -2, +4, and +6 in compounds, while tellurium often has an oxidation state of +4.

Summary & Key Takeaways

• Group 16 elements have two types of oxidation states: negative and positive.

• Oxygen typically has a common oxidation state of -2, but can also have an oxidation state of 0 or -1 in certain molecules.

• Sulfur, another element in Group 16, commonly has an oxidation state of -2, but can exhibit oxidation states of +2 and +4 in certain compounds.
