Answer to For the molecule NH4+ 1. Solution 99 In Japanese, Molecular Geometry of NO3. The main difference between electron geometry and molecular geometry is that electron geometry is found by taking both lone electron pairs and bonds in a molecule whereas molecular geometry is found using only the bonds present in the molecule. Since the molecule is symmetrical, the bond polarity of the four N-H bond cancel out causing the molecule to have zero molecular polarity. The molecular geometry of NH2- is also not symmetrical due to lone pairs of electrons as mentioned earlier. Tel +44 117 92 88310.
