Ответ:
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.
