CAS 7440-38-2
:Arsenic
Description:
Arsenic, with the CAS number 7440-38-2, is a metalloid element that exhibits both metallic and non-metallic properties. It is typically found in nature in various forms, including elemental arsenic, arsenic sulfides, and arsenic oxides. Arsenic is known for its gray, metallic appearance, although it can also exist in other allotropes, such as yellow and black arsenic. It has a relatively high melting point and is brittle in its solid state. Arsenic is primarily used in the production of semiconductors, alloys, and as a doping agent in various materials. However, it is most notorious for its toxicity and potential carcinogenic effects, making it a significant environmental and health concern. Arsenic compounds can be found in pesticides, herbicides, and some wood preservatives. In terms of chemical behavior, arsenic can form various oxidation states, with +3 and +5 being the most common in its compounds. Due to its hazardous nature, the handling and disposal of arsenic require strict regulatory compliance to mitigate risks to human health and the environment.
