Notes

  1. Commercially available lithium materials have atomic weights that range between 6.939 and 6.996; if a more accurate value is required, it must be determined for the specific material.
  2. Within the European Union, the following additional hazard statement (EUH014) must also be displayed on labelling: Reacts violently with water.
