WebMar 4, 2024 · Explanation: In an ammonium ion (N H + 4) ion, there is one nitrogen atom and four hydrogen atoms. Nitrogen has an atomic number of 7, and hydrogen has an atomic number of 1, and so the total atomic number of the hydrogens will be 1 ⋅ 4 = 4. So, there will be a total of 7 + 4 = 11 protons. NH4+ has 4 hydrogen atoms, therefore, there are 4 hydrogen electrons. Nitrogen’s valence electron count, however, is 5, owing to its position in the 5th group of the periodic table. The plus sign denotes the absence of 1 electron; therefore, it is minus one. If we total out the number of electrons, it will be (1×4) + (5×1) … See more Lewis Structure is a simplified arrangement and presentation of the electrons present in the valence shell of a molecule. A Lewis Structure is a depiction of the arrangement of … See more As mentioned earlier, NH4+ is made up of Nitrogen and Hydrogen. If we look towards the periodic table, we will find Hydrogen in group 1. This means that Hydrogen has 1 electron. NH4+ has 4 … See more The concept of Hybridization decrees that atomic orbits fuse with one another to form new degenerated hybrid orbitals, which influence bonding properties and molecular geometry … See more While the Lewis Structure is a 2-dimensional depiction of an atom of a molecule, molecular geometry is the visualization and designing of the atoms in a 3-dimensional space.
