Verified step by step guidance1
Step 1: Understand the classification of elements in the periodic table. Elements are generally classified into metals, nonmetals, and metalloids based on their physical and chemical properties.
Step 2: Recall that metalloids have properties intermediate between metals and nonmetals. They are typically found along the 'stair-step' line that divides metals and nonmetals on the periodic table.
Step 3: Identify the elements given: Na (Sodium), Fe (Iron), Si (Silicon), and Cl (Chlorine).
Step 4: Recognize that Na and Fe are metals, Cl is a nonmetal, and Si is located along the metalloid line, exhibiting properties of both metals and nonmetals.
Step 5: Conclude that Si (Silicon) is classified as a metalloid based on its position and properties in the periodic table.
