Magnesium (Mg).
Reason: Reactivity of metals increases down a group, so Mg (above Sr in Group 2) is less reactive than Sr. Alkali metals (like Na) are generally more reactive than alkaline earth metals in the same period, and Mg has higher ionization energies than Na, so Mg is less reactive than Na. Rb and Cs are below Na and Sr (more reactive); Ba is below Sr (more reactive).
