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? Before knowing this reason, first of all I want to ask you a simple question.
