Verified step by step guidance1
Understand the classification of elements: Metals, nonmetals, and metalloids. Metalloids have properties intermediate between metals and nonmetals.
Recall that metalloids are typically found along the 'stair-step' line on the periodic table, which separates metals and nonmetals.
Identify the elements given: Si (Silicon), Cl (Chlorine), Fe (Iron), and Na (Sodium).
Check the position of each element on the periodic table: Si is located along the stair-step line, indicating it is a metalloid.
Confirm that Cl is a nonmetal, Fe is a metal, and Na is a metal, so the metalloid among the options is Si.
