1)
a) Calcium Oxide - CaO.
b) Strontium Oxide - SrO
c) Barium Oxide - BaO
d) Radium Oxide - RaO
2)
a) Sodium Fluoride - NaF
b) Potassium Chloride - KCl
c) Lithium Bromide - LiBr
d) Rubidum Iodide - RbI
This occurs because the ions present are identical but opposite. For example, Calcium is +2 ions and Oxide is -2 ions. They cross-multiply and then cancel down.
