Lithium werd in 1817 ontdekt door Johan Arfwedson. De naam is afgeleid van het Oudgriekse λίθος (lithos) dat 'steen' betekent. Arfwedson ontdekte het element tijdens het onderzoeken van mineralen die afkomstig waren uit de Utö-mijnen op het Zweedse eiland Utö. Christian Gmelin observeerde in 1818 dat lithiumzouten in een vlam een heldere rode kleur gaven. Geen van beide was echter in staat lithium te isoleren. De eerste isolatie van lithium gebeurde tijdens de elektrol… WebThe mass of one atom is usually expressed in atomic mass units (amu), which is referred to as the atomic mass. An amu is defined as exactly 1 12 1 12 of the mass of a carbon-12 atom and is equal to 1.6605 × 10 −24 g. Protons are relatively heavy particles with a charge of 1+ and a mass of 1.0073 amu.
