      Calcium (Ca) and strontium (Sr) are expected to show chemical reactions similar to magnesium (Mg). This is because the number of valence electrons (2) is same in all these three elements. And since chemical properties are due to valence electrons, they show same chemical reactions.

      Beryllium and Calcium. These elements show chemical reactions similar to magnesium because magnesium, calcium and beryllium belong to same group, i.e. Group 2nd in the Modern Periodic Table.
