The element Arsenic was discovered in pre history, and has use in hardening bronze. [And in modern times, the lead plates in auto batteries.] As to where, the Mesopotamian civilizations knew of this material, and the element may be obtained from the sulphide mineral by simple roasting. It is toxic to life forms, and finds use in timber preservatives, and pest sprays. The timber preservation application is coming under an increasing cloud due to soil contamination, and this is not compatible with registered organic food production.
What else can I help you with?

Which element was discovered first copper or arsenic?
Copper was discovered first, since it occurs naturally in its pure form and has been used by humans since ancient times. Arsenic, on the other hand, was discovered later and is a metalloid that is typically found in combination with other elements in minerals.
What are the chemicals in arsenic?
Arsenic is a chemical element with the symbol As and atomic number 33. Its most common forms are inorganic arsenic compounds such as arsenic trioxide and arsenic pentoxide. These compounds are highly toxic to humans and can be found in certain pesticides, wood preservatives, and some types of metal alloys.
What element has the number of proton of 33?
