1 The table below compares the melting point and ion charges for sodium chloride and magnesium oxide. 2  MgO has a higher melting point than NaCl because 2 electrons are transferred from magnesium to oxygen to form MgO while only 1 electron is transferred from sodium to chlorine to form NaCl.
Lithium is used primarily for bipolar disorder. It is sometimes used when other treatments are not effective in a number of other conditions, including major depression, schizophrenia, and some psychiatric disorders in children. In mood disorders, of which bipolar is one, it decreases the risk of suicide.

The practical difference between Lithium batteries and Lithium-ion (Li-ion) batteries is that most Lithium batteries are not rechargeable but Li-ion batteries are rechargeable. From a chemical standpoint Lithium batteries use lithium in it's pure metallic form.
