which lists only metalloids? arsenic (as), sulfur (s), and polonium (po) antimony (sb), tellurium (te), and gallium (ga) boron (b), germanium (ge), and tellurium (te) polonium (po), aluminum (al), and silicon (si)

Answer

Answer:

C. boron (B), germanium (Ge), and tellurium (Te)

Explanation:

Step1: Recall metalloid elements

Metalloids are elements that have properties intermediate between metals and non - metals. The commonly recognized metalloids are boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and polonium (Po) in some cases.

Step2: Analyze each option

  • Option A: Sulfur (S) is a non - metal, not a metalloid.
  • Option B: Gallium (Ga) is a metal, not a metalloid.
  • Option C: Boron (B), germanium (Ge), and tellurium (Te) are all metalloids.
  • Option D: Aluminum (Al) is a metal, not a metalloid.
