Lithium - Alkali Metals

Lithium can be corrosive to the eyes, skin and respiratory tract. Inhalation of lithium can cause lung odeoma. Environmental Concerns: Metallic lithium typically reacts with nitrogen, oxygen, and water vapor in air. When this occurs, the lithium surfaces is coated with a mixture of lithium hydroxide, lithium carbonate, and lithium nitride.
