1) 4Na + O2 = 2Na2O (when sodium interacts with oxygen, sodium oxide is formed);

2) 2Ca + O2 = 2CaO (when calcium interacts with oxygen, calcium oxide is formed);

3) 2Zn + O2 = 2ZnO (when zinc interacts with oxygen, zinc oxide is formed);

4) 4Al + 3O2 = 2Al2O3 (when aluminum interacts with oxygen, aluminum oxide is formed);

5) 4Li + O2 = 2Li2O (when lithium interacts with oxygen, lithium oxide is formed).
