WebThe result is that the newly formed chloride ion, Cl ^- −, has 17 protons and 18 electrons. Because electrons carry a 1- charge, the net charge on the chloride ion from the extra electron is 1-. It has become an anion, or a negatively charged ion.

Web2 days ago · In hydronium ion, the central atom is oxygen and it has 6 valence electrons. Thus by the formula, V = 6. 3 hydrogen atoms are bonded to oxygen, so the number of the monovalent atoms (M) = 3. As this is a cationic molecule thus, C = 1. So, H = ½ [ 6 + 3 – 1] = 4. Thus we can say hybridization of H3O+ is Sp3. WebThe permanent dipole of each water molecule polarizes all adjacent water molecules. The dipole of a water molecule induces change in the dipoles of all nearby water molecule. Dipole-induced dipole interactions are always attractive and can contribute as much as 0.5 kcal/mole (2.1 kjoule/mole) to stabilization of molecular associations. WebA reliable estimate of the water electron affinity (which the researchers of the study provided for both bulk water and its surface) will help scientists establish computational protocols that are more robust and more reliable, and improve computational screening of materials. how to say underwriter in spanish
