How can you tell what atom has a shorter or longer bond length when comparing atoms and ions? For example, rank the molecules from smallest to largest N-O bond length.
NO2-, NO3-, NO+, NO

Re: Bond lengths
Drawing out all the molecules helps.
Single bonds are the longest and weakest, while triple bonds are the shortest and strongest.
So, NO+, for example, has one triple bond, so you know it will have a shorter N-O bond length than NO2- which has one double bond and one single bond.
