What is antimony?

Antimony is a chemical element with atomic number 51. It is a brittle, bluish-white metal with a metallic luster. It has a flaky appearance and lower electrical conductivity in its solid state than in its liquid state.

It is stable in air at room temperature, but when heated it emits white fumes, Sb₂O₃. It is commonly found in minerals along with copper, silver, and lead.
