Question

which properties are characteristic of metalloids? high electrical conductivity and a high melting point low electrical conductivity and a low melting point intermediate conductivity and a high melting point intermediate conductivity and a low melting point

Explanation:

Metalloids have properties intermediate between metals and non - metals. They show intermediate electrical conductivity (not as high as metals and not as low as non - metals) and often have high melting points.

Answer:

C. intermediate conductivity and a high melting point
