* Sembol: As
\n * Atom numaras\u0131: 33
\n * Atom a\u011f\u0131rl\u0131\u011f\u0131: 74.9216 g\/mol
\n * Oda ko\u015fullar\u0131nda (25 \u00b0C 298 K): Metalik gri kat\u0131

1250 y\u0131l\u0131nda ilk kez Albertus Magnus taraf\u0131ndan izole edilmi\u015ftir. 1649 y\u0131l\u0131nda Johann Schroeder arseni\u011fin eldesi hakk\u0131nda iki methot yay\u0131nlad\u0131.<\/p>\n
