Guida verificata passo dopo passo1
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 'stair-step' line on the periodic table.
Identify the given elements: Fe (iron) is a metal, Na (sodium) is a metal, Cl (chlorine) is a nonmetal, and Si (silicon) is a metalloid.
Recognize that silicon (Si) exhibits properties of both metals and nonmetals, such as semiconducting behavior, which is characteristic of metalloids.
Conclude that among the options, Si is classified as a metalloid because it fits the criteria and position on the periodic table.
