What is the significance of the first ionization energy of s in determining the reactivity of an element?

The first ionization energy of an element, like sulfur (s), is important in determining its reactivity. A low first ionization energy means it is easier for the element to lose an electron and form a positive ion, making it more reactive. Conversely, a high first ionization energy means it is harder for the element to lose an electron, making it less reactive.
