Ionization energy, also called ionization potential, is the energy necessary to remove an electron from the neutral atom. In contrast, ions are atoms or assemblies of atoms that have a net electrical charge. Likewise, to calculate the number of electrons for an ion that carries a negative charge, you must recall that when an ion carries a negative charge, the number of electrons are more than the number of protons. Typical densities of various substances are at atmospheric pressure. Each Na+ ion is surrounded by 6 Cl− ions, and each Cl− ion is surrounded by 6 Na+ ions. It rarely occurs in its elemental state or as pure ore compounds in the Earth's crust. How can I find the net charge of a molecule?
