A electronegativity difference of about 2 between the elements is considered a prerequisite for an ionic bond.
Figure 2 is arbitrary and different authorities have slightly different views.
Electronegativity is used to determine the type of bonding in a compound. If the electronegativity difference between atoms is large (typically greater than 1.7), the bond is considered ionic, with electrons transferred from one atom to another. If the electronegativity difference is small (typically less than 1.7), the bond is considered covalent, with electrons shared between atoms.
If the difference in electronegativity between the two atoms is greater than 2.0, then the bond is ionic. If one of the elements is a metal the rule is then relaxed a little to a difference of 1.6. Compounds on the "boundary of the rules" such as aluminium chloride Al, 1.61 Cl, 3.16 exhibit ionic and covalent tendencies. Al2Cl6 in the solid is ionic but in the liquid and vapour dimerises to form Al2Cl6 molecules.
Magnesium oxide has ionic bonding between the magnesium cation and the oxygen anion. Ionic bonds form between atoms with a large difference in electronegativity. Therefore, the bonding in magnesium oxide is considered polar.
Bonding type can be classified based on electronegativity difference as follows: Nonpolar covalent bond: Electronegativity difference less than 0.5. Polar covalent bond: Electronegativity difference between 0.5 and 1.7. Ionic bond: Electronegativity difference greater than 1.7.
Yes, beryllium nitride primarily exhibits ionic bonding due to the large electronegativity difference between beryllium and nitrogen. While there may be some covalent character in the bonding, the overall nature is primarily ionic.
Not sure about your examples but electronegativity variance is a good rule of thumb for deciding ionic from covalent bonds. Electronegativity variance less than 1.4, generally much less, indicates a covalent bonding. Electronegativity variance greater than 1.4 indicates ionic bonding.
Ionic bonding involves elements that have large differences in electronegativity. Typically, one element will have a low electronegativity (metals) and will lose electrons, while the other element will have a high electronegativity (nonmetals) and will gain electrons to achieve a stable octet configuration.
The electronegativity difference between the bonding atoms is concerned to determine it ionic behaviour.

In ionic bonding electrons are transferred from one element to another and are localised and not shared. the force of attraction in ionic bonding is electrostatic. In covalent bonding electrons are shared, or in some cases delocalised as in benzene. The source of the strength of a covalent bond is a quantum effect.
Large differences in electronegativity (greater than 1.7) result in ionic bonding between atoms. In ionic bonds, one atom (typically a metal) transfers electrons to another atom (typically a nonmetal) to achieve a stable electron configuration. This results in the formation of oppositely charged ions that are held together by electrostatic forces.
Bonding type can be classified based on electronegativity difference as follows: Nonpolar covalent bond: Electronegativity difference less than 0.5. Polar covalent bond: Electronegativity difference between 0.5 and 1.7. Ionic bond: Electronegativity difference greater than 1.7.

Silicon carbide exhibits a combination of covalent and ionic bonding. The silicon and carbon atoms form covalent bonds, while there is also a difference in electronegativity that leads to some ionic character in the bonds.
Ionic bonding involves the donation of electrons from one atom to another, resulting in the formation of positively and negatively charged ions that are attracted to each other. This occurs when one atom has a significantly higher electronegativity than the other atom.
