I-Mg-I

```

Magnesium iodide is an ionic compound, meaning that it is composed of positively and negatively charged ions. In magnesium iodide, magnesium has a +2 charge, while iodine has a -1 charge. The electron dot structure shows the transfer of electrons from magnesium to iodine, resulting in the formation of two iodide ions and one magnesium ion. The dots represent the valence electrons of each atom, and the lines represent the bonds between the atoms.
