ARSENIC
Arsenic may appear to be a poisonous element. This is because it is used as a poison for
murder both in real life cases and in made up books. But there are a lot of chemical uses
for arsenic such as it being a specimen.
Arsenic is also known arsenic in French, Arsen in German, arsenico in Italian and
arsenico in Spanish. 
The atomic number of the element arsenic is 33. The atomic weight is 74.92160(2). It's
symbol on the periodic table is As and its electronic configuration is [Ar].3d10.4s2.4p3.

Arsenic occurs in two solid modifications: yellow, and gray or metallic. Its color is
tin- white which tarnishes to dark gray or black. Its luster is metallic but the tarnish
will dull the luster. The transparency of crystals of arsenic are opaque. Its hardness is
3.4. Its specific gravities are 1.97 and 5.73, respectively. Arsenic is steel gray, very
brittle, crystalline, semi-metallic (metalloid) solid. It tarnishes in air, and oxidizes
to arsenous oxide when it is heated rapidly. Arsenous oxide has a garlic odor. Its is
associated with the minerals silver, dyscrasite, barite, cinnabar and nickeline. 
Arsenic seems to be known as poisonous. When you heat arsenic and certain minerals that
contains arsenic, it sublimes. 
Arsenic's discoverer was known since ancient times but we do not know when or where it
was discovered. The word arsenic roots from the Greek word arsenikon meaning yellow
orpiment.
Arsenic's physical data includes its standard state, color, density of solid at ambient
temperature/kg m-3, and molar volume per squared centimeter. Arsenic is solid at 298 K in
its standard state. Its color is metallic gray and has a density of 5727. Its molar
volume per squared centimeter is 12.95. 
There is two types of temperatures calculated per K. Its melting point is 1090 per K and
its boiling point is 887 per K. 
Isotopes: The nominal mass of Arsenic is 75As. Its accurate mass is 74.921594(17). It has
100% natural abundance. 
Arsenic is used in minor ores of arsenic and as mineral specimens. Arsenic is used in
bronzing, pyrotechnic, hardening and improving the sphericity of shot, d as a doping
agent in solid-state devices such as transistors. The arsenide is also used as a laser
material to convert electricity directly into covalent light. 
Arsenic, despite its poisonous reputation, it may be a necessary ultratrace element for
humans. It is a necessary ultratrace element for red algae, chickens, rats, goats, and
pigs.
