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