What is a semiconductor?
a. a conductor that operates only at low temperatures.
b. a conductor that conducts electricity faster than common metals.
c. a conductor that has less conductivity than do metallic
conductors
d. a substance that completely blocks the flow of electricity.

C. A conductor that has less conductivity than do metallic

conductors

Explanation:

Semi means less

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

can you list the answers so i can answer
