Lithium radioactif
WebThe atomic number of lithium, is 3 and the symbol used to represent it is Li. It is observed to be solid at room temperature and under standard conditions its observed melting point is around 180°C and melts at 1342°C. The reason for such high values is high energies of binding and ionization. WebTHE recent results of Mile.
