Question
Out of strontium (Sr), Beryllium (Be), Calcium (Ca) and Magnesium (Mg) in Group 2, which one is the most reactive?Group of answer choicesMgCaSrBe
Solution
The most reactive element in Group 2 is Strontium (Sr). This is because reactivity in Group 2 elements increases as you move down the group in the periodic table. This is due to the increase in atomic size and the decrease in ionization energy, making it easier for the atom to lose its outermost electrons and thus react. So, out of Strontium (Sr), Beryllium (Be), Calcium (Ca) and Magnesium (Mg), Strontium (Sr) is the most reactive.
