HUMAN STUDIES: Exposure to 37.5% ethylene for 15 min may result in marked memory disturbances.Figure 15.4.3 15.4. 3: The ammonium ion. When drawing the Lewis structure of a polyatomic ion, the charge of the ion is reflected in the number of total valence electrons in the structure. In the case of the ammonium ion: 1 N 1 N atom = 5 = 5 valence electrons. 4H 4 H atoms = 4 × 1 = 4 = 4 × 1 = 4 valence electrons.The Lewis Structure for water is useful because it allows to determine the molecular geometry and the polarity of the molecule. Because of the two lone pairs, H 2 O will have a bent molecular geometry and it will be a polar molecule. Remember that Hydrogen only needs two electrons to have a full outer shell.
