by hybridisation u can draw the structure of the molecule first find the hybridisation of the central atom.

Structure of I₃^- wud be lyke that of XeI2, hence Bond Angle about - 180

N with a -ve charge is Equivalent to an Oxygen atom, hence NO₂^- & O₃ bond angles are around 116⁰

Also dwn the group, angles decrease, so Bond angle PH₃ < NH₃.....hence the least amongst all...
n some standard bond angles such as ammonia's v must remember....
