## waheguru Group Title I have a question about naming molecular compounds we usually add a ide in the ending for the second elelemtn but what if there is only one element for example 03 would it be trioxygen or trioxide one year ago one year ago

1. waheguru Group Title

So do I add the ide as the ending for oxygen if it is the only element or do i make a trioxygen

2. zepp Group Title

It would be Trioxide of ________ if you were talking about some compound

3. waheguru Group Title

It is a compound with is self

4. waheguru Group Title

three oxygens

5. zepp Group Title

Although, if you want to talk about $$\large \text{O}_3$$, it would be trioxygen

6. waheguru Group Title

yes 03,

7. zepp Group Title

So trioxygen would be correct and for my previous post, it should be _____ trioxide, my bad.

8. waheguru Group Title

So its tripxygen because there is only one compound right?

9. zepp Group Title

Yes, in this case we could simply call it ozone ;x

10. waheguru Group Title

But say it was CO then it would be carbon oxide right

11. zepp Group Title

Yes

12. zepp Group Title

Monoxide*

13. waheguru Group Title

Just clarifying, for any compound that is with it self does not have the ending of ide but if it with a different compound then is does

14. zepp Group Title

Mono - 1 Di - 2 Tri - 3 Tetra - 4 Penta - 5 and so on.

15. waheguru Group Title

yes

16. zepp Group Title

What do you mean?

17. waheguru Group Title

So if an element is bonded with it self we dont add the ide but when its bonded with another we add the ide

18. zepp Group Title

Just for some on the elements, not all elements are like this

19. zepp Group Title

It's just a language thing, we add the ide because gen doesn't sound right sometimes

20. waheguru Group Title

n2 would be dinitrogen right?

21. zepp Group Title

Yep

22. waheguru Group Title

Thank You!

Welcome! :)

There's a modern trend to naming allotropes of elements where there are identifiable molecules as if they were compounds, hence O2 is "dioxygen" and N2 is "dinitrogen" and so forth. But few chemists actually use those names. To most working chemists, O2 is "oxygen" and N2 is "nitrogen," because that's how the elements naturally occur. If you actually had some O you would call it "atomic oxygen" or something like that, because it's a rare and strange beast. It also runs into a little trouble with some elements, e.g. sulfur naturally occurs as S8 and phosphorus as P4, and saying "octasulfur" and "tetraphosphorus" sounds...well, strange. Then we get into the fact that one of the allotropes of carbon is C60....
