I have to draw a dot and cross diagram for NH2+ and then state the bond angles. I have done NH2-, but I am not sure how to do the + one.
I would take the structure you've drawn for NH2^- and remove one pair of the two lone pairs. It leaves an ion that doesn't obey the rule of eight but I don't see another way to do it.
Ok, thank you. That was the only way I could think of doing it too. What would the bond angles therefore be?
