A _____ generally has properties that are similar to those of metals and nonmetals. Under some conditions, a _____ may behave like a metal. Under other conditions, it may behave like a nonmetal. The behavior often can be controlled by changing the conditions. For example, like most nonmetals, pure silicon is a poor conductor of electric current. However, if a small amount of boron is mixed with silicon, the mixture is a good conductor of electric current.
