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 ... Web7 sep. 2024 · Ions — electrically charged atoms — can carry a positive or negative charge. Positive ions are cations and are typically metals like copper or sodium. Negatively-charged ions are anions, formed from nonmetallic elements like oxygen and sulfur. Formation of Ions – Each of the elements on the periodic table is capable of forming an ion.
