CHEMICAL AND PHYSICAL PROPERTIES
Physical Description | Sodium appears as a silvery soft metal that becomes grayish white upon exposure to air. Shipped as a solid or molten liquid. Burns violently with explosions that may spatter the material. Used for making gasoline additives, electric power cable, sodium lamps, other chemicals. |
