The common sense method is the best way to figure out the formal charge.Since N is a group five element it has five VE in its non bounded neutral ground state.If it has more or less than five VE than it will incur a formal charge.Assume that R is another H,then you will get the amide ion which has a formal charge of -1 on the N,since N accounts for six of total of eight VE around the central atom.All of LP are counted and only half of the bounded pair since H accounts for the other two.In the case of ammonia,there is no formal charge on N,since it has five,the same as it its ground state.One LP plus one half of six gives you 5.In the ammonium ion,N will have a formal charge of plus one,since there are no LP,all of the bounded pairs will have to be divided by two,hence eight electrons around the central atom N,cut in half is 4.But it is supposed to have five in its ground state,hence 5-4 is one.H does not incur a formal charge in any of the examples since it has only one its magic number.

@gabrielpetit2911

Another way to look at it is if the atom is making more or fewer bonds than its valency then it will have a formal charge. Every "extra" bond means a negative charge and every "missing" bond means a positive charge. This kinda breaks down when the octet rule is broken, so like Xenon Difluoride, but it works well for molecules with atoms from periods 1 and 2.

in the first example with the R-N-H, where did the 4th electron come from? N in nature has 5 valence e, R bonds N leaving N with 4e and then H comes along and takes 1e leaving N with 3 valence e. Hence 3 dots representing 3 electrons, not 4.

@ronlal652

Before you can assign FC on a polyatomic ion you have to first draw its Lewis dot structure. N has 5 VE, C has four VE ,and you will have to add one e to account for the -1 charge, thus giving you 10 VE for this structure.This is the best way to complete the ocet .With triple bond both C and N will have 8 VE around it.For this ion C will be assigned the -1 FC not N,since N has 5 VE in its ground state,and this is the same as in this ion,half the bonded e plus the LP will equal 5,and 5-5=0 hence no FC on N,the C gets the FC of -1.See my above explaination to assign FC.

I suggest you draw out the Lewis dot structure for this polyatomic ion, namely,the hydronium ion,H3O +.O has 6 VE,one for each H,gives 9VE,but you subtract one e due to the plus one charge on this ion.You now have 8VE to draw this structure.You will have 3 bonded pairs,and one lone pair.Hence 6-5 =1,the FC is assigned to O of plus one.Good luck,you need to get a good tutor.
