Alkali metal toxicity. Alkali metal cations do not usually form coordination complexes with simple Lewis bases due to their low charge of just 1 and their relatively large size. Thus the Li ion forms most complexes and the heavier alkali metal ions form less and less though exceptions occur for weak complexes. 90 Lithium in particular has a very rich coordination chemistry in which it exhibits coordination.
Lithium is an element of the alkali-metal group with atomic number 3 atomic weight 694 and an emission line at 671 nm on the flame photometer. The empirical formula for Lithium Citrate is C 6 H 5 Li 3 O 7. Lithium acts as an antimanic.

Caesium atomic clock. A primary frequency standard in which electronic transitions between the two hyperfine ground states of caesium-133 atoms are used to control the output frequency. Fears about lithium toxicity delayed its approval for many years but it is now the major drug for the treatment of manic episodes and for maintenance therapy in bipolar patients.

Chemical properties are any of the properties of matter that can be observed and measured only by performing a chemical change or chemical reaction. Chemical properties cannot be determined by touching or viewing a sample. The structure of the sample must be altered for the chemical properties to become apparent.
