A fiery temperament of alkali metals

Chemistry Level 1

The alkali metals are a group in the periodic table consisting of the chemical elements lithium (\(\ce{Li}\)), sodium (\(\ce{Na}\)), potassium (\(\ce{K}\)), rubidium (\(\ce{Rb}\)), cesium (\(\ce{Cs}\)), and francium (\(\ce{Fr}\)). Because of their high reactivity, they must be stored under oil to prevent reaction with air. They are found naturally only in salt and never as a free element. Which of following best explains their high reactivity?
