There are also many isomers, the longest-lived of which is 120m1 Sb with half-life 5.76 days. Except for beryllium , antimony is the lightest element observed to have isotopes capable of alpha decay ; 104 Sb is seen to undergo this mode of decay.
Antimony is a chemical element; it has symbol Sb (from Latin stibium) and atomic number 51. A lustrous grey metal or metalloid , it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3 ).
Sb 2 O 3; Fool's gold – a mineral, iron disulfide or pyrite; can form oil of vitriol on contact with water and air. Fulminating silver – principally, silver nitride, formed by dissolving silver(I) oxide in ammonia. Very explosive when dry. Fulminating gold – a number of gold based explosives which "fulminate", or detonate easily.
This is a list of 194 sources that list elements classified as metalloids. The sources are listed in chronological order. The sources are listed in chronological order. Lists of metalloids differ since there is no rigorous widely accepted definition of metalloid (or its occasional alias, 'semi-metal').
Antimony(III) sulfate was first produced in 1827 by the reaction of antimony(III) oxide and 18 molar sulfuric acid at 200 °C: [1]. Sb 2 O 3 + 3 H 2 SO 4 → Sb 2 (SO 4) 3 + 3 H 2 O. The concentration of the sulfuric acid is important, as a lower concentration will produce basic antimony oxides, while a higher concentration will produce antimony(III) pyrosulfate.
Stibnite, sometimes called antimonite, is a sulfide mineral with the formula Sb 2 S 3.This soft grey material crystallizes in an orthorhombic space group. [6] It is the most important source for the metalloid antimony. [7]
2 Sb + 3 S → Sb 2 S 3. Sb 2 S 3 is precipitated when H 2 S is passed through an acidified solution of Sb(III). [9] This reaction has been used as a gravimetric method for determining antimony, bubbling H 2 S through a solution of Sb(III) compound in hot HCl deposits an orange form of Sb 2 S 3 which turns black under the reaction conditions.
