History
The atomic number is 51 and the chemical symbol is Sb. The name derives from the Greek anti + monos for not alone or not one because it was found in many compounds. The chemical symbol Sb comes from the original name stibium which is derived from the Greek stibi for mark since it was used for blackening eyebrows and eyelashes. The name was changed from stibium to antimonium to antimony. The minerals stibnite (Sb2S3) and stibine (SbH3) are two of more than one hundred mineral species which were known in the ancient world.Holden, Norman E., (2004).
