Answer:
The compound formed by iodine and magnesium, with iodine having a charge of -1 and magnesium having a charge of +2, is called magnesium iodide. In this compound, the magnesium atom donates two electrons to the iodine atom, resulting in the formation of a stable ionic compound.
To understand why the compound is named magnesium iodide, let's break it down:
1. Magnesium: Magnesium is a metal that belongs to Group 2 of the periodic table. It tends to lose two electrons to achieve a stable electron configuration. When it loses these two electrons, it forms a magnesium ion with a charge of +2.
2. Iodide: Iodine is a non-metal that belongs to Group 17 of the periodic table. It tends to gain one electron to achieve a stable electron configuration. When it gains this electron, it forms an iodide ion with a charge of -1.
When magnesium and iodine combine, the magnesium ion (Mg^2+) and the iodide ion (I^-) attract each other due to their opposite charges. This attraction leads to the formation of an ionic bond, resulting in the compound magnesium iodide (MgI2).
So, in summary, the name of the compound formed by iodine and magnesium with charges of -1 and +2 respectively is magnesium iodide.
