Q
Q: Which alkaline earth metal is least reactive?
Solution: Beryllium (Be) is the least reactive alkaline earth metal.
Steps: 5
Step 1: Understand what alkaline earth metals are. They are a group of elements in the second column of the periodic table.
Step 2: Identify the alkaline earth metals. They include Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra).
Step 3: Learn about the reactivity of these metals. Generally, as you move down the group in the periodic table, the reactivity increases.
Step 4: Compare the reactivity of Beryllium with the other alkaline earth metals. Beryllium is at the top of the group and does not react as easily as the others.
Step 5: Conclude that Beryllium (Be) is the least reactive alkaline earth metal.
