What characteristics does arsenic metal have?

Arsenic is a metalloid, nit a true metal. Therefore, it exhibits properties of both metals & nonmetals. read more

Arsenic is a metalloid, nit a true metal. Therefore, it exhibits properties of both metals & nonmetals. Arsenic has a similar electronegativity and ionization energies to its lighter congener phosphorus and as such readily forms covalent molecules with most of the nonmetals. read more

Arsenic doesn't seem much like a metal in its so called yellow form, but it also has a grey form known tellingly as metallic arsenic. Yellow arsenic has a specific gravity of 1.97 while grey arsenic has a specific gravity of 5.73. Grey arsenic is the usual stable form with a melting point of 817 degree Celsius. read more

Yellow arsenic is metastable, is a poor electrical conductor and does not have a metallic sheen. It is prepared by cooling gray arsenic vapor in liquid air. It reverts to gray arsenic at room temperature. Black arsenic can be prepared by cooling arsenic vapor at 100 o C - 200 o C. It is glassy, brittle and a poor electrical conductor. read more

The presence of sulfur is another factor that affects the transformation of arsenic in natural water. Arsenic can precipitate when metal sulfides form. In this way, arsenic is removed from the water and its mobility decreases. When oxygen is present, bacteria oxidize reduced sulfur to generate energy, potentially releasing bound arsenic. read more
