Input: Antimony is a chemical element with symbol Sb (from Latin: stibium) and atomic number 51. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb2S3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl. The 8-hour time-weighted average (TWA) is set at 0.5 mg/m3 by the American Conference of Governmental Industrial Hygienists and by the Occupational Safety and Health Administration (OSHA) as a legal permissible exposure limit (PEL) in the workplace. element has 6 valence electrons, shows properties of metals and nonmetals, and has 52 protons in the nucleus. Antimony - Applications. 1 About 60% of antimony is consumed in flame retardants, and 20% is used in alloys for batteries, plain bearings, and solders. [47] 2 Antimony is mainly used in the trioxide for flame-proofing compounds, always in combination with halogenated flame retardants except in halogen-containing polymers. Unit 3 Study Guide: Electron Configuration & The Periodic Table 1. For each of the following elements, state whether the element is radioactive, synthetic or both. Berkelium - Radium - Radon - Francium - 2. For each of the following substances, state whether it is an element or compound. brass (Cu + Zn) - methane (CH4) - carbon (C) - water (H2O) - Electrons always fill orbitals in the same order. Each s orbital holds 2 electrons, each set. of p orbitals holds 6 electrons, each set of d orbitals holds 10 electrons, and each set of f. orbitals holds 14 electrons. The order in which orbitals are filled, from first to last, is: 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f 6d 7p. Aluminum has 13 electrons. 31. Antimony is like a nonmetal in that it is a brittle, crystalline solid, has poor electrical and heat conductivity, and has a low boiling point. However, it is also like a metal because of its shiny silver appearance and ability to form alloys. Into which group should antimony be placed? 32. A lustrous gray metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb2S3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name, kohl.[4] Metallic antimony was also known, but it was erroneously identified as lead upon its discovery. 15. Hydrogen is a nonmetal yet it is positioned in group 1 on the periodic table because: Antimony - Precautions. 1 The effects of antimony and its compounds on human and environmental health differ widely. 2 For oral absorption, ICRP (1994) recommended values of 10% for tartar emetic and 1% for all other antimony compounds. 3 Antimony is mainly excreted from the human body via urine. Query: how is antimony like a nonmetal
Output:
Antimony is like a nonmetal in that it is a brittle, crystalline solid, has poor electrical and heat conductivity, and has a low boiling point.
