'''Arsenic''' is a [[chemical element]] with an [[atomic number]] of 33, and [[atomic mass]] of approx. 74.92, and is the 20th most abundant element in the Earth's crust. Many of its compounds are highly toxic. It bears a chemical similarity to [[phosphorus]] which is the cause of some of its toxic effects. The most common [[oxidization state|charges]] for arsenic to possess are -3, +3, and -5.
