Free Gift for you: Interactive Periodic Table The alloy formed by mixing antimony and lead is used in manufacturing battery components, cable sheathing, etc.The compounds of antimony are used in manufacturing of glass, paints, ceramics, etc.Antimony is a metalloid and hence it is used in semiconductor devices like diodes, infrared detectors, etc. When antimony is heated in air, it forms antimony trioxide.Antimony can be dissolved in oxidizing acids like sulfuric acid or nitric acid.When antimony is reacted with acids, it does not easily dissolve into it.The black allotrope of antimony easily gets corroded when kept open in air. When antimony is kept open in air, it does not react easily.Chemical properties of AntimonyĬhemical properties of antimony are mentioned below. Antimony has many isotopes, but out of them the most abundant isotope is 121Sb (around 57%).The crystal structure of antimony is Rhombohedral.The melting point of antimony is 630.6 ☌ and its boiling point is 1635 ☌.The atomic mass of antimony is 121.76 u and its density is 6.7 g/cm 3. Antimony is hard and brittle which can not be malleable.Antimony is a poor conductor of heat and electricity at room temperature.Antimony is solid at STP and has a silvery grey metallic lustre.Physical properties of antimony are mentioned below. The physical and chemical properties of antimony element are mentioned below. In ancient times, antimony was used as a reflecting surface in mirrors.China is the leading producer and supplier of antimony in the world (more than 80%).The abundance of antimony in the earth’s crust is estimated to be 0.2 to 0.5 part per million.Antimony is very rarely found in its pure form, but it is mostly found from the mineral stibnite.The name antimony was derived from the Greek words “anti” and “monos” which means a metal that is not found alone.Interesting facts about antimony element are mentioned below. So the last electron of antimony enters the p-subshell or p-orbital. The simple answer: The elements will lie in the s, p, d or f block will completely depend upon the subshell in which the last electron will enter.įor example the electron configuration of antimony is 4d 10 5s 2 5p 3. How can you determine the blocks-wise position of elements? Naturally occurring isotopes are marked in green light green = naturally occurring radionuclides.Before knowing this reason, first of all I want to ask you a simple question. Isotones and IsobarsThe following table shows the atomic nuclei that are isotonic (same neutron number N = 73) and isobaric (same nucleon number A = 124) with Antimony-124. Nuclear isomers or excited states with the activation energy in keV related to the ground state. Name of the isotope: Antimony-124 Sb-124 Symbol: 124Sb Mass number A: 124 Atomic number Z: 51 (= number of protons) Neutrons N: 73 Isotopic mass: 123.9059358(16) u ( atomic weight of Antimony-124) Nuclide mass: 123.8779599 u (calculated nuclear mass without electrons) Mass excess: -87.62024 MeV Mass defect: 1.1256797 u (per nucleus) Nuclear binding energy: 1048.56388647 MeV (per nucleus) 8.45616037 MeV (average binding energy per nucleon) Separation energy: S N = 6.46750(6) MeV (first neutron) S P = 7.0930(27) MeV (first proton) Half-life: 60.20(3) d Decay constant λ: 1.332647310969 × 10 -7 s -1 Spin and parity: 3- Year of discovery: 1939
