मैग्नेशियम की तरह रासायनिक अभिक्रियाशीलता दिखाने वाले दो तत्वों के नाम लिखीए? आपके चयन का क्या आधार है?
Option A
Option B
Option C
Option D
Solution
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.
