Antimony is stable in air at room temperature, but reacts with oxygen if heated to form antimony trioxide, Sb < sub > 2 </ sub > O < sub > 3 </ sub >.

Antimony is sometimes found natively, but more frequently it is found in the sulfide stibnite ( Sb < sub > 2 </ sub > S < sub > 3 </ sub >) which is the predominant ore mineral.

Thus numbers like 2 and 120 ( 2 × 60 ), 3 and 180 ( 3 × 60 ), 4 and 240 ( 4 × 60 ), looked the same because the larger numbers lacked a final sexagesimal placeholder.
