How does nitrogen usually exist? What changes occur when you ionise it?

.... dont know ?it has the arrangement 2,5 so when ionised it would have a 3- charge. what has this got to do with working out the first ionisation energy. do i have to do the  1s2 etc

Isnt it just...

N  :rarrow: N+ +1e- or sommin?

in the gaseous state, of course

write an equation including state symbols to show the first ionisation energy of nitrogen

I would say question is unclear. No idea what equation can 'show first ionisation energy'. What endtherapture51 proposed is just an equation of the first ionisation, it doesn't 'show' the energy.

the first ionisation energy of nitrogen

so when ionised it would have a 3- charge

Obviously you have no idea what 'first' means.

And be sure your attitude is not helping your case.

The first ionisation (potential) of an element is the energy required to remove one mole of electrons from one mole of isolated atoms in the gaseous phase to give a +1 ion.
For exampe, the firs ionisation energy of a sodium atom is: Na (g)  :rarrow: Na+ (g) + e-

No, this is first ionisation reaction equation, not first ionisation energy. Energy involved in this reaction is the one we are interested in, but the reaction equation can't 'show the energy'. This is a lousy wording.
