Reactivity is a chemical property that measures the tendency of an element or compound to undergo a chemical reaction. Calcium (Ca) and magnesium (Mg) are both alkaline earth metals, which are known for their high reactivity. They react with water to form hydroxides, with acids to form salts, and with oxygen to form oxides. However, the relative reactivity of calcium and magnesium differs due to differences in their atomic radii, ionization energies, and electronegativities.
