In the short form: elements are striving to completely fill valence shells of electrons to reach a quantumly stable energy state. They react to take electrons away from elements willing to give up electrons or share outer shell electrons with elements they aren't strong enough to steal from.

An element's reactivity is influenced by its ability to gain or lose electrons to achieve a stable electron configuration. Elements with incomplete outer electron shells are generally more reactive as they can easily form bonds with other elements to gain stability. Reactivity can also be affected by factors such as atomic size and electronegativity.

The amount of valence electrons. More valence electrons leads to more reactivity.
