It is ionic. The dichromate ion, Cr2O72-, with the structure [O3Cr-O-CrO3]2-, consists of covalently bonded oxygen and chromium atoms (the electronegativities of Cr and O are 1.6 and 3.5, respectively, so the bonds are highly polar). This oxyanion is bonded ionically to magnesium ions, Mg2+. See Cotton and Wilkinson, Advanced Inorganic Chemistry, for more on the dichromate ion. Magnesium dichromate is the only alkaline earth dichromate that is appreciably soluble in water.

Is magnesium phosphate a covalent or ionic?
no. it only has ionic as far as i know.
Is magnesium oxid a covalent compound?
Magnesium oxide is an ionic compound, not a covalent compound. It is formed through the transfer of electrons from magnesium to oxygen, resulting in the formation of ionic bonds between the two elements.
Is lead chromate an ionic or covalent compound?
Lead chromate is an ionic compound. Lead (Pb) is a metal and chromate (CrO4) is a polyatomic ion, so they form an ionic bond by transferring electrons.

Magnesium oxide is an ionic compound, not a covalent compound. It is formed through the transfer of electrons from magnesium to oxygen, resulting in the formation of ionic bonds between the two elements.
Is MgCl2 covalent?
No, MgCl2 is not covalent. It is an ionic compound formed by the transfer of electrons from magnesium to chlorine atoms. Magnesium loses two electrons and each chlorine gains one electron to form the ionic bond.
Is magnesium ionic or covalent bond?
Magnesium typically forms ionic bonds, as it readily loses its two valence electrons to achieve a stable octet configuration. This creates a magnesium cation with a 2+ charge that can then form ionic bonds with anions.
Is magnesium sulfide a ionic or covalent compound?
It depends on the rule you use to classify it. Magnesium Sulfide is ionic, if using the metal-nonmetal rule. It is polar covalent, if using the 1.7 electronegativity difference rule. Both these rules are generalizations.
