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.

Antimony exists in several allotropic forms, which are physically distinct conditions resulting from different arrangements of atoms. The most stable form is a brittle, silvery solid with a high metallic luster.1

Other identified allotropic forms include:

Explosive antimony: An unstable amorphous form produced through electrolytic deposition. It is termed "explosive" because it converts to the stable metallic form in a mildly explosive manner when scratched or bent.1
Black antimony: An amorphous form that results from the sudden quenching of antimony vapor.1
Yellow antimony: A form produced by the low-temperature oxidation of stibine ( $S b H_{3}$ ) with air or chlorine.1
