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.

How does electronegativity influence molecular bonding?
Chemical bonding cannot be solely explained with the concept of electronegativity. According to generality, it is said that a particular compound has a principal ionic character if it exceeds the electronegativity difference of 1.7 in Pauling's scale.
CaCO3 ionic bonding?
Calcium is a metal with an electronegativity of 1.0 and oxygen is a nonmetal with an electronegativity of 3.5. The electronegativity difference is 2.5, and anything over 1.7 indicates an IONIC BOND.
Explain how can you calculate the Energetics of Covalent Bonding and the Ionic character?
To calculate the the Energetics of Covalent Bonding and the Ionic character, you need to take into accot the difference in electronegativity of two atoms: Δχ = χB − χA.
Is O2 is an example of a nonpolar polar or ionic?
Non polar covalent bonding. (Both atoms have the same electronegativity)
Is sodium hydrogen carbonate ionic or covalent?
Sodium hydroxide is an ionic compound which disassociates in to Na+ and OH- ions in solution.
Why CuS is covalent compound while CuO is ionic compound?
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.

What large differences in electronegativity result in bonding between atoms?
If this difference is under 2 the bond is covalent; if the difference is over 2 the bond is ionic.

What are the rules for determining if a compound is covalent?
The electronegativity difference between the bonding atoms is concerned to determine it ionic behaviour.
Is O2 is an example of a nonpolar polar or ionic?
Non polar covalent bonding. (Both atoms have the same electronegativity)
Is sodium hydrogen carbonate ionic or covalent?
Sodium hydroxide is an ionic compound which disassociates in to Na+ and OH- ions in solution.
How is electronegativity related to the position of elements on the periodic table and covalent bonding?
The difference in electronegativity between the atoms determines the nature of the bond. The larger the electronegativiity difference the more ionic character it will have, this ranges from polar covalent through to ionic bonding.In valence bond terms the ionic resonance forms become more important and make a bigger contribution as the electronegativity difference increases. The contribution of covalent bonding never really disappears.
What does bonding is on a continuum mean?
To say that bonding is on a continuum means that the type of bonding changes gradually as the difference in electronegativity between atoms increases. There is no sharp distinction between polar covalent and ionic bonds.
What type of bonding is present in cadmium sulphide?
CdS is about 15% ionic and the balance covalent, based on an equation that curve fits measured ionic character of compounds versus difference in electronegativity.
Is ammonia a ionic or covalent compound?
Ammonia is a covalent compound. It is a compound of two nonmetals, nitrogen and hydrogen, so the difference in electronegativity is not great enough to cause ionic bonding.
