The increasing order ofelectronegativityfor the given elements is: silicon < sulfur < phosphorus < chlorine.The elements arranged in order of increasing electronegativity are silicon, sulfur,phosphorus, and chlorine.Electronegativity is a measure of an atom's tendency to attract electrons towards itself in achemicalbond. In general, electronegativity increases across a period from left to right on the periodic table.Silicon, with an electronegativity value of 1.90, has the lowest electronegativity among the given elements. Sulfur follows with an electronegativity of 2.58, indicating a slightly higherelectron-attracting ability. Phosphorus has an electronegativity of 2.19, placing it between sulfur and chlorine. Chlorine has the highest electronegativity among the elements listed, with a value of 3.16, indicating its strong ability to attract electrons.To learn more aboutelectronegativityclick here:brainly.com/question/29597673#SPJ11...
