Antimony is like a nonmetal in that it is a brittle, crystalline solid, has poor electrical and heat conductivity, and has a low boiling point. However, it is also like a metal because of its shiny silver appearance and ability to form alloys. Which of the following statements best describes antimony?

Antimony is metalloid

Explanation:

From the properties of the metals given, we can conclude that antimony is pure a metalloid.

A metalloid has the properties of metals and non-metals.

Most metalloids will only conduct heat and electricity under certain conditions so they are poor conductors. As expected of a metal, it should be malleable and ductile but antimony is brittle and a crystalline solid. Although, it can form an alloy. We can see that most of the properties of this metal is in between those of true metals and non-metals. Therefore, antimony is a metalloid.
