OverviewAI-generated

Arsenic is a chemical element with the symbol As and atomic number 33. Its standard atomic weight is 74.921595. The element has an electronegativity of 2.18 and an ionic radius of 0.58. It exhibits oxidation states of -3, 1, 2, and 3. The density of arsenic is 5.73.

Arsenic melts and sublimes at 1135. It has a vapor pressure of 0. The minimal lethal dose is 338, while the median lethal dose (LD50) is 1000. Safety limits include a time-weighted average exposure limit of 0.5 and a ceiling exposure limit of 0.002. The level immediately dangerous to life or health is 5. The element was discovered or invented in 1300.
