WebThis results in a cation with 20 protons, 18 electrons, and a 2+ charge. It is symbolized Ca 2+, and has the same number of electrons as atoms of the preceding noble gas, argon. The name of a metal ion is the same as the name of the metal atom from which it forms, so Ca 2+ is called a calcium ion. WebThe mobile ions in the anion resin bead are chloride anions (Cl —). This is also the standard delivery form for many anion resins. Each ion going into the bead has to be replaced by an ion getting out of the bead, again to preserve electrical neutrality. This is what is called ion exchange. Only ions of the same electric sign are exchanged ...
