Definition

Arsenic is a chemical element with the symbol As and atomic number 33. It is a highly toxic metalloid that is naturally found in the Earth's crust. Arsenic is a silvery-grey, brittle, and odourless solid. It is soluble in water and can be found in both organic and inorganic forms.

Arsenic is a naturally occurring element, but it can also be found in some man-made products, such as pesticides and herbicides. Arsenic poisoning can occur when people are exposed to high levels of arsenic in their environment or through their diet. Symptoms of arsenic poisoning can include nausea, vomiting, diarrhoea, abdominal pain, and skin rashes. In severe cases, arsenic poisoning can lead to death.

Arsenic has been used for centuries as a poison, and it is still used in some countries today. However, arsenic is also used in some industrial applications, such as the production of glass and semiconductors.
