The answer is: D) MgF₂.The fluoride of magnesium is the salt, ionic compound.1) Magnesium (Mg) is the metal of 2. group of the Periodic table of the elements and has a low ionization energy and electronegativity, which means that you can easily lose the valence electons (two valence electrons).Magnesium has atomic number 12, meaning it has 12 protons and 12 electrons. Lost two electrons to form cation magnesium (Mg2⁺) with electronic configuration as stable as the nearest noble gas neon (Ne), with 10 electrons.The electron configuration of the magnesium ion: ₁₂Mg2⁺ 1s2 2s2 2p⁶.2) Fluorine (F) is not a metal with higher electronegativity, what that meand is easily gain electrons.The fluorine-jas atomic number 9, which means it has 9 protons and 9 electrons. Gain an electron to form the fluoride anion (F⁻) with electronic configuration as stable as the nearest noble gas neon (Ne), with 10 electrons.The electronic configuration of fluoride ions: ₉F⁻ 1s2 2s2 2p⁶.
