Magnesium chloride (MgCl2) is non-volatile in nature due to its strong ionic bonding. Ionic compounds like MgCl2 consist of positively charged metal ions (Mg2+) and negatively charged non-metal ions (Cl^-) held together by electrostatic forces of attraction. These bonds are very strong, requiring a considerable amount of energy to break them and convert the compound into a gaseous state. As a result, MgCl2 does not readily evaporate or become volatile at normal temperatures and pressures.
