Question.
Name two elements you would expect to show chemical reactions similar to magnesium. What is the basis for your choice?

solution:
Calcium (Ca) and Strontium (Sr) are expected to show chemical reactions similar to nagnesium $(\mathrm{Mg})$. This is because the number of valence electrons $(2)$ is same in all these hree elements. And since chemical properties are due to valence electrons, they show same hemical reactions.
