I have to draw lewis structures and resonance structures for these molecules

F2
O2
NH3
CO
CO2
NO2-
ClO2+

I've looked on the net but I don't understand what a resonance structure is, can somebody explain please? :confused:

Is this degree level?
There is a wiki page on 'resonance structures'

yes, i'm only in my 2nd week tho ^^ I understand resonance now, do you know if NO2- is the only one with a resonance structure?

i've drawn ClO2+ but it has 10 electrons in its outer shell? is this possible?

yes, it's possible - it's called octet expansion, however it's not necessary to describe the bonding in this ion.

I'm not really sure what you have drawn...

What is that on the oxygen atom at the top - it looks like a bond going nowhere!

OK - makes sense.

The resonance structures are simple although as with all benzene rings you have to chase the electron pairs around the ring.

Start off with the electron pair on the oxygen (negative charge).
