WebAt your level it's enough to know that metals generally form positive ions and non-metals form negative ions. The size of the charge is equal to the number of electrons needed to get to the "closest" 8 (or two in the case of period 2 metallic elements). So Aluminium is 2,8,3. It could go to 2,8,8 or 2,8. The latter is "closer" (lose three vs ...
WebThe bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Another atom, typically a non-metal, is able to acquire the electron(s) to become a negative ion, or anion.
