Question

1. choose the best answer.

what are the eight metalloids?
copper (cu)
antimony (sb)
silicon (si)
tellurium (te)
nickel (ni)
astatine (at)
polonium (po)
arsenic (as)
germanium (ge)
boron (b)

Explanation:

Metalloids have properties intermediate between metals and non - metals. Boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po), and astatine (At) are the eight metalloids. Copper (Cu) and nickel (Ni) are metals.

Answer:

B. antimony (Sb), C. silicon (Si), D. tellurium (Te), F. astatine (At), G. polonium (Po), H. arsenic (As), I. germanium (Ge), J. boron (B)
