The most reactive family of metals on the periodic table is the alkali metals. This group includes elements such as lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). Alkali metals are highly reactive due to their single valence electron, which they readily lose to form positive ions. Reactivity increases as you move down the group because the outer electron is further from the nucleus and is more easily removed. They react vigorously with water and halogens, and their reactivity with air can also lead to oxidation.

In contrast, alkaline earth metals are reactive but not as much as alkali metals. Transition and inner transition metals generally exhibit lower reactivity compared to these two main groups. Hence, the correct answer to your question is alkali metals.
