Chemical properties Arsenic is a metalloid. A metalloid is an element that has properties of both metals and nonmetals. Metalloids occur in the periodic table on either side of the staircase line that starts between boron and aluminum. When heated in air, arsenic combines with oxygen to form arsenic oxide (As 2 O 3 ).
Apr 08, 2019· The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for the hazardous substance described here. Each peerreviewed profile identifies and reviews the key literature that describes a hazardous substance's toxicologic properties. Other pertinent literature is also presented, but is described in less detail than the key studies.
The number of electrons in each of antimony's shells is 2, 8, 18, 18, 5 and its electron configuration is [Kr] 4d 10 5s 2 5p 3. The antimony atom has a radius of 140 pm and a Van der Waals radius of 206 pm. Antimony was discovered around 3000 BC and first isolated by Vannoccio Biringuccio in 1540 AD.

Pewter is an alloy. A metal alloy is produced by combining a metal with two or more elements that enhance the properties of the metal. Modern pewter is an alloy comprised primarily of the following elements: tin, antimony and copper.
Jun 11, 2004· In the 12% antimony alloy, S rises from −110 μv/°K at 300°K to −220 μv/°K at 20°K. A specimen of this material, doped with % lead, is p type below 42°K. A qualitative explanation of these results is given in terms of mixed conduction by electrons and holes having properties similar to those in pure bismuth.
Antimony and tellurium are primarily used in metal alloys. Tellurium gets its name from the Latin word "tellus" which means "earth." Antimony has been known about since ancient times and was used as a cosmetic by the Ancient Egyptians. Antimony gets its name from the Greek words "anti monos" meaning "not alone."
Apr 25, 2017· Groups contain elements with similar properties that have the same electron arrangement in their outer shells, known as "valence electrons," which determine the properties of the element and it's chemical reactivity, and how it will take part in chemical bonding. The Roman numerals above each group dictate the usual number of valence electrons.
Jul 12, 2013· Antimony occurs naturally in the environment and is predominantly found in Russia, Bolivia, china, and South Africa.

Physical Properties. Oxygen changes from a gas to a liquid at a temperature of °C, and then can be solidified or frozen at a temperature of °C. Oxygen exists in all three allotropic forms. The three allotropic forms include normal oxygen, diatomic oxygen, or dioxygen; nascent, atomic, or monatomic oxygen; and ozone or triatomic oxygen.
Antimony is a metalloid which means that it has metallic and nonmetallic properties and it is element 51 in the periodic table lying in the diagonal metalloids in the p group.
