![]() In the pure form, it is neither ductile nor malleable like true metals.It is stable in air and water, being slightly oxidized by air and insoluble in water.It also indicates the use of antimony sulfide as eye makeup. Antimony is graphically represented by the Eye of Horus, a symbol of royal power, good health, and protection from ancient Egypt.Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and. The mineral, measuring 9 X 10 X 4 inches, was obtained from the Lushi Mine, China. Element Antimony (Sb), Group 15, Atomic Number 51, p-block, Mass 121.760. The stibnite crystals, resembling a group of swords and made from sulfur and antimony, were auctioned on 2nd June 2013 with an opening bidding price of $32,500.may cause respiratory, gastrointestinal, cardiovascular, reproductive, and dermal effects. ![]() Exposure to antimony compounds like antimony trisulfide, antimony tribromide, antimony pentasulfide, etc. ![]() Also, antimony trioxide is considered to be carcinogenic to humans. While these are the most common valences, the real behavior of electrons is less simple. It occurs either during the treatment of parasitic diseases, including schistosomiasis and leishmaniasis or because of occupational exposure. You may assume that the valences of the elementsthe number of electrons with which an atom will bond or formare those that can be derived by looking at the groups (columns) of the periodic table. State of matter at room temperature (solid/liquid/gas)Īntimony Trisulfide (Stibnite) Antimony Toxicity An atom of antimony has 5 valence electrons, as indicated by its presence in column 15 of a wide form periodic table. Valence Electron Potential (-eV): 57 Physical Properties of Antimony Atomic Mass Average: 121.757 Boiling Point: 1860 K 1587° C 2889° F Coefficient of lineal thermal expansion /K-1: 8.5E -6 Conductivity Electrical: 0.0288 10 6 /cm Thermal: 0.243 W/cmK Density: 6.684g/cc 300K Description: Hard brittle bluish-white metal.
