Lewis Structure and More Ammonium nitrate is made up of two components: ammonium (NH4) and nitrate (NO3). There has to be a pi orbital or a free p orbital for a compound to have a resonance structure. NH4+ is known as an ammonium ion, but NH4 would not make sense as it is not balanced. Remember that uncharged nitrogen has 3 bonds and one lone pair and hydrogen has one bond and no lone pairs. The reason for learning to draw Lewis structures is to predict the number and type of bonds that may be formed around an atom. (The actual connectivity is H-O-N-O, but you could also draw a reasonable Lewis structure for H-NO2, with formal charges on N and O.) It contains 3 polar covalent bonds and 1 coordinate covalent bond. In order to come up with this answer, you first need to know the number of valence electrons for Nitrogen.
