## waheguru 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

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

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

3. waheguru

It is a compound with is self

4. waheguru

three oxygens

5. zepp

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

6. waheguru

yes 03,

7. zepp

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

8. waheguru

So its tripxygen because there is only one compound right?

9. zepp

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

10. waheguru

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

11. zepp

Yes

12. zepp

Monoxide*

13. waheguru

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

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

15. waheguru

yes

16. zepp

What do you mean?

17. waheguru

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

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

19. zepp

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

20. waheguru

n2 would be dinitrogen right?

21. zepp

Yep

22. waheguru

Thank You!

23. zepp

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....
