of these nonmetals, which one is likely to be the least reactive?\no oxygen (o)\no sulfur (s)\no chlorine (cl)\no fluorine (f)

Answer

Brief Explanations:

Reactivity of non - metals generally decreases down a group in the periodic table. Oxygen is in Group 16, sulfur is below oxygen in Group 16, chlorine is in Group 17 and fluorine is above chlorine in Group 17. Among these, sulfur is the largest atom and has the least tendency to gain electrons compared to the others as its outermost electrons are farther from the nucleus and less attracted to it.

Answer:

sulfur (S)
