Question

calcium, magnesium, and strontium are near each other on the periodic table and have some characteristics in common, but they differ in chemical reactivity. which lists these metals in order from most reactive to least reactive? calcium, magnesium, strontium magnesium, calcium, strontium strontium, calcium, magnesium strontium, magnesium, calcium

Explanation:

In the periodic table, for metals in the same group, reactivity increases down the group. Calcium (Ca), magnesium (Mg), and strontium (Sr) are in Group 2. Strontium is below calcium and magnesium. So strontium is the most reactive, followed by calcium, and then magnesium.

Answer:

C. strontium, calcium, magnesium
