The type of bonding that exists in MgCl2 is ionic bonding.

Here's why:

1. Magnesium (Mg) is a metal and Chlorine (Cl) is a non-metal.
2. In general, when a metal and a non-metal combine, they do so by ionic bonding. This is because metals tend to lose electrons to achieve a stable electron configuration, while non-metals tend to gain electrons to achieve a stable electron configuration.
3. In the case of MgCl2, Magnesium loses 2 electrons to become Mg2+ and each Chlorine atom gains one electron to become Cl-. This transfer of electrons results in the formation of ions, which are then attracted to each other due to their opposite charges, forming an ionic bond.

So, MgCl2 is held together by ionic bonds.
