Chlorine magnesium silicon and sulfur in order from increasing nonmetallic character?

The order of increasing nonmetallic character among chlorine, magnesium, silicon, and sulfur is magnesium, silicon, sulfur, and chlorine. Magnesium is a metal and exhibits the least nonmetallic character. Silicon is a metalloid, followed by sulfur and chlorine, which are both nonmetals, with chlorine being the most nonmetallic due to its high electronegativity and reactivity.
