Verified step by step guidance1
Understand the classification of elements on the periodic table: metals, nonmetals, and metalloids. Metalloids have properties intermediate between metals and nonmetals.
Recall that metalloids are typically found along the 'stair-step' line that divides metals and nonmetals on the periodic table.
Identify the given elements: Fe (iron) is a metal, Na (sodium) is a metal, O (oxygen) is a nonmetal, and Si (silicon) is a metalloid.
Recognize that silicon (Si) is located along the metalloid line and exhibits properties of both metals and nonmetals, which classifies it as a metalloid.
Conclude that among the options, Si is the element classified as a metalloid.
