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.

no. it only has ionic as far as i know.
Ionic
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.
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.
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.
