Is it possible for nitrogen to form pentavalent compounds?

2. Please don't list 100 homework questions and then say you need help immediately. It is your own responsibility to start your homework early.  If you do have a lot of questions, put them in one post but don't expect them to all be answered at once. Violators will have their multiple posts deleted and subject to banning.


4. Please show that you've at least attempted the problem. We don't mind helping you solve problems but we are ethically opposed to doing homework for you. Violators will have their topic deleted or locked, and subject to banning.

Why not?!
Nitrogen can also form pentavalnet compound for example N2O5 or HNO3 many salts and so on...

Neither N2O5 nor HNO3 contain pentavalent nitrogens.

Does pentavalent mean that element has valence 5 ...Or I was thinking about wrong term :S

N+52O-25 ??

In that context it means the sum of bonding and non-bonding pairs in an element.

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex
