– Alkali metals (Group 1) are generally more reactive than alkaline earth metals (Group 2).
– Within alkali metals, reactivity increases down the group.
– Within alkaline earth metals, reactivity generally increases down the group (though sometimes variations occur, but the general trend holds for Ca vs Mg).
– The order of reactivity for the given options is approximately K > Na > Ca > Mg.
