It comes from environmental causes.

Contaminated air, food, and water can all be the source of Arsenic Ingestion.

It is very brittle and crystalline; arsenic sublimates (changes directly from a solid to a gas) when heated.

The atomic number is 33 and the atomic mass is 74.9216

Numbers of protons/electrons is 33 The element group is the nitrogen Group Number Neutrons are 42 Boiling point is 603.0 Celsius and the

melting point is 817 Celsius. Common isotopes are As-75 Density is 5.72 g/cm3 Most abundant physical state: Solid

(Metalloid solid) The symbol is AS

Arsenic is released into the air by volcanoes and is a natural contaminant of some deep-water wells.

The toxicity of an arsenic-containing compound depends on its valence state, and the physical aspects governing its absorption and elimination.

Arsenic accumulates in the liver, spleen, kidneys, lungs, and gastrointestinal tract.

Odor of element is garlic. No one knows when Arsenic was

discovered and they leave it to the ancients.
