Question

20 multiple choice 1 point which of the following elements would likely have the highest reactivity with sodium? selenium (se) arsenic (as) sulfur (s) phosphorus (p)

Explanation:

Reactivity of non - metals with sodium depends on their electronegativity and position in the periodic table. Sulfur is closer to the top - right of the periodic table among these elements and has a relatively high electronegativity. It can more readily accept electrons from sodium to form a compound. Selenium is below sulfur in the same group, so its reactivity is lower. Arsenic and phosphorus are in different groups and have lower electronegativities compared to sulfur for this reaction context.

Answer:

C. Sulfur (S)
