Verified step by step guidance1
Understand the classification of elements into metals, nonmetals, and metalloids based on their physical and chemical properties.
Recall that metalloids have properties intermediate between metals and nonmetals and are typically found along the zig-zag line on the periodic table.
Identify the elements given: Oxygen (O), Sodium (Na), Iron (Fe), and Silicon (Si).
Recognize that Oxygen is a nonmetal, Sodium is an alkali metal, Iron is a transition metal, and Silicon is a metalloid.
Conclude that Silicon (Si) is classified as a metalloid because it exhibits properties of both metals and nonmetals.
