Antimony: Sb 2 O 3, Sb 2 O 5; Bismuth: Bi 2 O 3, Bi 2 O 5; There are other oxides, such as Sb 4 O 10, that are not formed directly through reaction with oxygen. Arsenic(III) oxide and antimony(III) oxide are amphoteric, whereas bismuth(III) oxide acts only as a base (this is because it is the most metallic element in the group).

Antimony (Sb; CASRN ) is a silvery semimetal element with chemical properties similar to lead, arsenic, and bismuth. In nature, it is found associated with sulfur as stibnite. Antimony is used in white metal, a group of alloys having relatively low melting points. White metal usually contains tin, lead, or antimony as the chief component.
