Verified step by step guidance1
Understand that metalloids are elements with properties intermediate between metals and nonmetals, often semiconductors.
Recall common examples of metalloids, which include elements like Silicon (Si), Germanium (Ge), Arsenic (As), and Boron (B).
Review the given pairs and identify which elements are metalloids: Silicon (Si) and Germanium (Ge) are known metalloids.
Recognize that Sodium (Na) and Magnesium (Mg) are metals, Oxygen (O) and Nitrogen (N) are nonmetals, and Iron (Fe) and Copper (Cu) are metals.
Conclude that the pair Silicon (Si) and Germanium (Ge) correctly represents metalloids.
