Sodium chloride contains Na+and Cl-ions: 1. this is one positive charge and one negative charge 2. the charges are balanced 3. so the formula is NaCl See more Magnesium oxide contains Mg2+and O2-ions: 1. this is two positive charges and two negative charges 2. the charges are balanced 3. so the formula is MgO See more Aluminium oxide contains Al3+and O2-ions: 1. this is three positive charges and two negative charges 2. to balance, we need two Al3+ions and three O2-ions 3. so the formula is Al2O3 See more WebThe Formation of Ionic Bonds. Ionic compounds are formed when metal atoms react with non-metal atoms. Metal atoms lose their outer electrons which the non-metal atoms gain to form positive and negative ions. The positive and negative ions are held together by strong electrostatic forces of attraction between opposite charges.
WebExamples of simple ionic compounds are sodium chloride, NaCl, or magnesium oxide, MgO. Ionic bonds form between elements on opposite sides of the periodic table. Periodic trends like atomic radius and the charge of ions will influence ionic bond strength in compounds. These can be explained in terms of electrostatic theory. WebNaming Ionic Compounds.
