The Greek for orpiment was arsenikon, deriving from the Greek word arsenikos, meaning "male", from the belief that metals were of different sexes. This Greek term was used by Theophrastus in the fourth century BC. [5] The Chinese term for orpiment is Ci-Huang (in Pinyin), meaning "female yellow". [6]
Both orpiment and realgar, as well as As 4 S 3, have selenium analogs; the analogous As 2 Te 3 is known as the mineral kalgoorlieite, [39] and the anion As 2 Te − is known as a ligand in cobalt complexes. [40] All trihalides of arsenic(III) are well known except the astatide, which is unknown.
Arsenic blende or Arsenblende (German: Arsenblende, arsenik-blende) is a trivial name that has partially fallen out of scientific use, used by mineralogists, as well as representatives of mining and craft professions in relation to at least two similar ore minerals — orpiment and realgar, [1]: 135, 239, 438 in composition — arsenic sulfides.
Arsenic trisulfide is the inorganic compound with the formula As 2 S 3.It is a dark yellow solid that is insoluble in water. It also occurs as the mineral orpiment (Latin: auripigmentum), which has been used as a pigment called King's yellow.
It is a soft, sectile mineral occurring in monoclinic crystals, or in granular, compact, or powdery form, often in association with the related mineral, orpiment (As 2 S 3). It is orange-red in color, melts at 320 °C, and burns with a bluish flame releasing fumes of arsenic and sulfur.
[2] [3]: 219 While the mineral orpiment is considered to be the oldest yellow pigment, Naples yellow, like Egyptian blue, is one of the oldest known synthetic pigments. [ 4 ] [ 3 ] : 219 Naples yellow was used in ancient Egypt and Mesopotamia, finding widespread application during the Hellenistic and Roman periods.
41 of the 118 known elements have names associated with, or specifically named for, places around the world or among astronomical objects. 32 of these have names tied to the places on Earth, and the other nine are named after to Solar System objects: helium for the Sun; tellurium for the Earth; selenium for the Moon; mercury (indirectly), uranium, neptunium and plutonium after their respective ...

Oil of hartshorn is a crude chemical product obtained from the destructive distillation of deer antlers.; Salt of hartshorn refers to ammonium carbonate, an early form of smelling salts and baking powder obtained by dry distillation of oil of hartshorn.
