Covalent
Covalent bonding
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.
Beryllium is a metal, not a nonmetal. It will generally form ionic compounds with nonmetals.

Covalent.
Covalent
Beryllium nitride has an ionic bond.
Covalent bonding
ionic, beryllium is a metal and oxygen is a non metal... metal and non metal are always ionic bonding

It is an ionic solid.
ionic, because they're on opposite sides of the periodic table. same side=covalent, opposite=ionic.
Be3P2 Is an ionic compound made up of the group II metal beryllium, a cation is this compound and the nonmetal phosphorus, an anion is this compound. Be 2+ and P 3- combine ionicly to form Be3P2
As beryllium is smaller than barium and it is more polarising, it will distort the perfect ionic sphere and attract some outer shell electrons of barium and give it a covalent character.
No. Beryllium has only two valence electrons and forms ionic bonds with chlorine, not covalent bonds. Beryllium atoms form 2+ ions, and chlorine atoms form 1- ions in order to form the ionic compound beryllium chloride, BeCl2.
