Beryllium nitride has an ionic bond.
Nitride hydride is typically covalent. In this compound, nitrogen and hydrogen share electrons to form a covalent bond.

BeBr2 is a covalent compound. Beryllium (Be) and bromine (Br) are both nonmetals, so they form a covalent bond by sharing electrons.
In this case, Mg has a value of 1.3 and N has a value of 3.0, so it is an ionic bond. Ionic and covalent bonds are on a continuum. Some "ionic" compounds are in fact partly covalent because the positive cation (e.g. magnesium) polarizes (attracts the electrons of) the anion forming a stronger bond than if it was 100% ionic. A table of ELECTRONEGATIVITY can help one determine whether a bond is ionic or covalent. The bigger the difference in electronegativity the more ionic the bond.
Aluminum nitride (AlN) is a covalent bond. It is formed by the sharing of electrons between aluminum and nitrogen atoms.
No, it is ionic

The chemical formula for beryllium nitride is Be3N2.
Beryllium nitride is an ionic compound, consisting of beryllium cations (Be2+) and nitride anions (N3-). Ionic compounds typically form between metals and nonmetals, with transfer of electrons from the metal to the nonmetal to achieve full outer electron shells.
BeBr2 is a covalent compound. Beryllium (Be) and bromine (Br) are both nonmetals, so they form a covalent bond by sharing electrons.
Beryllium nitride (Be3N2) is the compound formed by the elements beryllium and nitrogen. It is a binary ionic compound with a 2:3 ratio of beryllium to nitrogen atoms.
In this case, Mg has a value of 1.3 and N has a value of 3.0, so it is an ionic bond. Ionic and covalent bonds are on a continuum. Some "ionic" compounds are in fact partly covalent because the positive cation (e.g. magnesium) polarizes (attracts the electrons of) the anion forming a stronger bond than if it was 100% ionic.

Aluminum nitride (AlN) is a covalent bond. It is formed by the sharing of electrons between aluminum and nitrogen atoms.
Potassium nitride, K3N, is an ionic compound. It consists of potassium cations and nitride anions held together by ionic bonds due to the transfer of electrons from potassium to nitrogen.
