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.
Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell.
