The researcher should select Arsenic (As).
Arsenic has a higher atomic mass than nitrogen and is in the same group (Group 15) of the periodic table, meaning it shares similar chemical properties. The other elements listed (Na, S, and Si) do not have the same reactivity as nitrogen. Sodium (Na) is an alkali metal, sulfur (S) is a chalcogen, and silicon (Si) is a metalloid, all of which have different reactivity patterns compared to nitrogen.
