Discussion Overview

The discussion revolves around identifying the three ions formed by oxygen, including their names and formulae. Participants explore the concept of ions, particularly in the context of a practice sheet, and clarify the distinction between simple ions and those involving multiple oxygen atoms.

Discussion Character

  • Exploratory
  • Homework-related
  • Conceptual clarification

Main Points Raised

  • One participant identifies "Oxide" as the ion with a 2- charge but seeks information on the other two ions.
  • Another participant suggests that the other two ions may be free radicals, prompting further exploration of the topic.
  • A participant mentions finding references to reactive oxygen species (ROS) and polyatomic ions involving oxygen, expressing uncertainty about whether these fit the original question.
  • Superoxide (O2-) and peroxide (O22-) are proposed by multiple participants as the other two ions involving only oxygen.
  • A participant reflects on the misunderstanding of the term "ion," indicating that the question may involve ions with multiple nuclei.

Areas of Agreement / Disagreement

Participants generally agree on the identification of superoxide and peroxide as relevant ions, but there is some uncertainty regarding the definition of "ion" and whether the discussion pertains strictly to ions of oxygen or includes ions of molecules containing oxygen.

Contextual Notes

There is a lack of consensus on the definition of "ion" as it relates to multiple nuclei, and some participants express confusion about the scope of the question, particularly regarding the distinction between simple ions and polyatomic ions.

Who May Find This Useful

This discussion may be useful for students studying chemistry, particularly those preparing for tests on ionic compounds and the properties of oxygen-related ions.

The Question:

- "Oxygen forms three separate ions. What are the names and formulae of the three ions?"

Now I am familiar with the ion "Oxide" which is the Oxygen atom with a 2- (negative two) charge, but I cannot find any information on these other two, any help would be greatly appreciated, thank you.

[SOLVED]

Answer: Oxide (one oxygen atom, negative two charge), Superoxide (two oxygen atoms, negative one charge), Peroxide (two oxygen atoms, negative two charge)A thanks to both Fewmet and Ygggdrasil for their help.

It is difficult to say anything without just giving you the answer...

Does it help to know that the other two ions are free radicals?
 
It seems I may have posted this on the wrong part of the forums, this question pertains to a practice sheet. It was stated that we could use the internet, I believe the issue for me was simply using the wrong search parameters, fortunately they brought me here. This is not an issue of a grade more so reference material. I would appreciate a straight answer but I understand if you wish for me to "figure it out".

To what you stated regarding radicals, I have found material referring to ROS and polyatomic ions involving oxygen such as superoxide, peroxide, and hydroxyl. I am not entirely sure if this is what I am looking for as I'd imagine the question refers to ions of Oxygen not ions of molecules containing Oxygen.
 
Superoxide (O2-) and peroxide (O22-) involve only oxygen and are probably what you are looking for.

That's what I was thinking, too.

Dometrios: From a teacher's perspective, I suspect the point of the question is to get you to see that "ion" can mean more than one nucleus is involved.
 
OK, thanks for clarifying that. So in truth the answer was right in front of me all along it was just that I misunderstood the definition of "ion". Thanks for the help, this should prove quite useful during our next test.
