NH4+ (ammonium) - Eurofins Agro
NH4+ (ammonium) Ammonium (NH4+) is rapidly taken up in the soil by soil life and then converted to nitrate (NO3-). The proportion of ammonium in soil is generally low. Higher levels are, for example, found after applying animal manure, and slow-acting fertilizers often also show higher ammonium levels. A crop can absorb ammonium. Visit website

NH4+ lewis structure: Drawings, Hybridization, Shape, Charges, …
In NH4+ lewis structure, the molecule is sp3 hybridized and has a bond angle of 109.50, so the molecule’s shape is tetrahedral. This structure has no double bond, so the molecule could not show a different resonance structure. There is a shortage of electrons over N in this molecule. So, the positive charge is on N only.
