A labeled periodic table entry for antimony shows its symbol Sb, atomic number 51, atomic weight 121.76, electron configuration, and name. It is a solid, weakly acidic other metal with a rhombohedral crystal structure at room temperature. — antimony Properties of antimony.

When heated, antimony reacts easily with halogens. This process results in the oxidation of the element.1

For example, the reaction with chlorine can produce two different chlorides:
* Antimony trichloride ( $S b C l_{3}$ ): A colorless, caustic, and hygroscopic crystalline solid.2
* Antimony pentachloride ( $S b C l_{5}$ ): A colorless to reddish-yellow, caustic, and oily liquid.2

The ability of antimony to exhibit a +5 oxidation state allows it to form both the pentafluoride and the pentachloride.1
