  • IONS AND FORMULAS
    • IONS - atoms that have lost or gained an electron - same electronic structure as a noble gas
    • Sodium Chloride contains Na  (+1) and Cl (-1) ions
      • (+1)+(-1)=0 The charges are balanced with one of each ion so the formula for sodium chloride = NaCl
    • Magnesium chloride contains Mg  (+2) and Cl  (-1) ions
      • Because a chloride ion only has 1  charge we will need two of them to balance out the 2  charge of a magnesium ion. This gives us the formula MgCl
  • (+1)+(-1)=0 The charges are balanced with one of each ion so the formula for sodium chloride = NaCl
